I think the proc bug is old, might have to do with /proc/bus/pci...
I have that on my G5 too with 2.6.26, I think I just forgot about it..
Care to give that untested patch a try ?
powerpc: Always enable pci domains in /proc for 64 bits powerpc
This patch always enable the use of the pci domain number in /proc
on 64 bits ppc machines instead of the old pseries specific hack of
testing for the buid which is meaningless on most machines.
We also enable the compat code that makes domain 0 use the old
format for the sake of the X server.
