FC3 and ATI Digital video

I am having problem when I use digital (DVI) versus analog video.

The hardware:

ASUS SK8V motherboard with an Opteron 140 and 2GB ram.  The video is an ATI 
9100 with both digital and analog video output (radeon driver).  The monitor 
is a Dell 2000FP (LCD) which can handle both analog and digital (DVI) input 
selectable on the monitor.  The is also a Belkin Omnicube 4 port KVM.

When I first started using the ASUS/Opteron system in my setup, I found that I 
could not use the analog video through the KVM ... the ASUS BIOS "overdrove" 
the monitor and it cut out.  However, FC1 did work OK for both install and 
running using this analog configuration.

My solution to the problem was to not use the analog/KVM setup but instead to 
connect the monitor to the ATI 9100 using the digital (DVI) interface and 
then use the selection on the monitor to switch to DVI input when I selected 
that ASUS/Opteron.  This worked fine with FC1 and FC2 (both i386 and x86_64).

I skipped this round of testing so my first exposure to FC3 was the final 
release.  I first installed it on another system and that went fine.  I then 
tried installing on the ASUS/Opteron ... oops, black screen and then the 
monitor went into powersave mode (turned off).  After several tries, I gave 
up and did a text everything install.  Install and bootup ... oops, X fails 
to start again.  OK, reboot and come up in non-X (3).  I ran 
system-config-display from another system via ssh and everything looked like 
it configured properly but X did not display.

After some fooling around, I switch to using the analog/KVM setup instead of 
the digital (DVI) setup.  That worked fine.  With this setup I also then 
installed the x86_64 FC3 and it worked fine too.

I noticed some laptops are also having problems and wonder if that problem is 

Question:  Is anyone using digital (DVI) video, an ATI video card and the 
radeon driver?  Does it work?  IS anyone having problems?
