I have have two recent G5s, one Quad 2.5GHz G5 PowerPCs and one Dual 2.7GHz G5 PowerPCs. I installed FC5 on them recently and I'm trying to get at least one of them running dual head.
The Quad has an NVIDIA GeForce 6600. Although there was an issue with some unreadable text during the graphical install, things are fine post installation with an increased color depth. From what I read, one head is as good as it will get. That is, the nv driver will not support dual head and there is no way to use something like fbdev to run two heads on one nv card. If someone could confirm this, I would appreciate it.
The Dual has an ATI Radeon 9600T. Under FC4, I'm pretty sure we had the "radeon" driver working, but regrettably I didn't save the xorg.conf file. Graphic install would not work and after fighting with all day, we have it running with the fbdev drivier. Basically we ended up running the YDL 4.1 install disk and looking at the xorg configuration file they used to get the graphical installer running.
However, I am assuming that I can't run dual head with fbdev, so now I'm stuck. If I try to run with the "radeon" driver, the machine hangs. not just no video, which I've had before with inproper monitor settings, but complete death as it stops responding to ping and I can't ssh login or ctrl-alt-del the machine. This seems to be a problem with the "radeon" driver in xorg 7.0.0, as discussed here:

Anyone out there have dual head working with a PowerMac G5 Desktop and FC5? I have some older machines I could try if anyone has it working on a slightly different box.

With a Radeon I found I had to use MergedFB instead of Xinerama. And I also required 'ReverseDDC', and it was picky about which way round I connected the two heads -- that's possibly less of an issue if you don't have one DVI and one VGA as I do.
My config is at http://david.woodhou.se/xorg.conf.g5 -- although that's actually what I'm using in FC4, because Evolution in FC5 is just too broken for me to want to update just yet. Drop the 'RgbPath' and it works in FC5 though -- at least for me.

Just curious how you are accessing the keys' 3rd level characters such as @ from the Q key or the Euro sign from the E key, since you do not have something like Option "XkbOptions" "lv3:lwin_switch" in your xorg.conf's "InputDevice" Keyboard0 section

@ on the Q key? That's a new one on me. My '@' is shift and ' as $DEITY intended for en_GB :)
The € sign is AltGr-4. Actually, it looks like AltGr-Q does give me '@'.
I actually use a standard PC keyboard on the G5 -- but it's much the same on the PowerBook, the key which replaces AltGr is the key just to the left of the cursor keys; right of the right-hand Apple key.
I don't actually remember if I did anything special to set that up.... yeah, on the PowerBook I have this in ~/.xmodmap:
keysym 0xff8d = ISO_Level3_Shift keycode 222 = XF86PowerDown

OK, those combinations seem to be specific for UK keyboards. I have a German keyboard in my iBook G4 - here is a photo: http://i5.ebayimg.com/02/i/06/9e/bc/d4_1_b.JPG
As you can see, the E key is associated with € and L with @. Under MacOS X, I have to press alt+E to get the €, while I access the € by pressing Apple+E in FC5. However, I had to add the mentioned
Option "XkbOptions" "lv3:lwin_switch"
to the "InputDevice" Keyboard0 section of /etc/X11/xorg.conf to get this working.
What also would be nice is to associate @ with the L key, as under MacOS, but I haven't found out yet how to do this.

When I press that key within the gedit text editor, the cursor moves down, so I prefer to press the Apple key to access 3rd level characters.

Doesn't work in FC5 for me with the current ATI driver. I followed the advice of the ubuntu thread and got a newer version of the driver which worked great. Specifically, I force installed this RPM and now have a the dual processor with ATI running two heads:

The Quad with nvidia wouldn't work with our Apple Cinema Display 22" at resolution 1600x1024. The output was clear but right 1/3 of the screen appeared on the left, offset from the mouse pointer even. I simply put an Apple Cinema Display 20" at 1280x1024 and it works fine. I think the 1600x1024 resolution was just too much for the "nv" driver to cope with somehow, although it worked fine with the ATI card. Fortunately the previous owner of the 20" monitor runs Mac OS X, and it wasn't hard to convince them to take the 22" monitor in exchange.
