I started out with YDL 4.0 on my PowerMac G5 Dual Processor 2.0GHz
machine and there were no problems with the fans.
Later I got some 2.5GHz models and 4.0 and 4.0.1 and the fans were
blaring because of a simple check needed for PowerMac7,2 versus
PowerMac7,3. I swtiched to FC4 at this point and that fixed my fan
problems...sort of. At this point I have some 2.7GHz machines that are
prematurely panicing about overheating, There is a fix for this in
2.6.15 for which there is a FC4 updates testing kernel. However, as I
just reported to the fedora-test-list, for some reason the driver
doesn't seem to be initialized I'm back to full blaring fans on those
machines for a while.
One problem I had with FC4 is that I couldn't get it to clean
install on
the new machines because of a disk druid problem or something like
that.
So I actually installed YDL all the way through the first reboot,
then I
turned around and installed FC4. if I tried to reboot just after the
partion part and not after actual package installation it didn't
work, I
think it wasn't flushing the right stuff to disk until the end. I just
did minimial packge installs to get through it quick.
Now, you have a different model that I have not tried. searching
through
my collection of recent FC4 updates and updates-testing kernels
(which I
happen to have around because of my own 2.7 GHz problem
investigation) I
see that the new windfarm driver is specifically for the PowerMac9,1:
mchammer:~/kernel $ grep 9,1 */*/drivers/macintosh/*.*
1823/linux-2.6.15/drivers/macintosh/windfarm_pm91.c: * PowerMac9,1
1823/linux-2.6.15/drivers/macintosh/windfarm_pm91.c: if
(machine_is_compatible("PowerMac9,1"))
1823/linux-2.6.15/drivers/macintosh/
windfarm_pm91.c:MODULE_DESCRIPTION("Thermal control logic for
PowerMac9,1");
1823/linux-2.6.15/drivers/macintosh/windfarm_smu_sensors.c: /*
Try to use quadratic transforms on PowerMac8,1 and 9,1 for now,
1823/linux-2.6.15/drivers/macintosh/
windfarm_smu_sensors.c: machine_is_compatible
("PowerMac9,1")) &&
However, this is the same updates-testing kernel that didn't work for
me, even though it has the patched therm_pm72.c driver I needed for my
PowerMac7,2 and PowerMac7,3 machines. But it seems like trying FC4 and
then doing a "yum --enablerepo=updates-testing update kernel*"
might get
you somewhere close.
Benjamin Herrenschmidt <benh(a)kernel.crashing.org> is the author for
most
of the thermal support for the PowerMacs. I never see him on the
fedora
lists. He can be found on linuxppc64-dev and also on debian-powerpc
On my web page (
http://carlstrom.com/winunix.html) I have links to the
various linux/ppc mailing lists such as linuxppc64-dev, fedora-ppc,
debian-powerpc, and yellowdog-devel if you want to look around the
archives for PowerMac9,1 stories.
As far as YDL goes, there is a 4.1 release now available for $$$ and
perhaps the ISO's will be out soon. there was a 4.0.91 beta that
people
seemed happy with as far as PowerMac support went. For me, the package
selection of FC4 is so much better than YDL that I don't want to go
back.
Good luck,

Wow, this is the first really informative response that I have gotten
as per this issue on any PPC Linux list!!!! Please tell me, if I try
to install Fedora Core 4 and do manual partitioning for "sdb" SATA
internal drive #2 on my G5 can I decide which drive to install Fedora
on? I just want to make sure that I don't have to bail because I
think Fedora is going to erase and install on my OS X install drive
"sda".
