Hi Ben,

I also encountered this problem on a dual G4 450 (AGP graphics).  On the
theory that more information is often useful (or at least easily deleted
from the email queue), I am sending the results of "lspci -vv" as well as
a couple of dmesg logs.  The last kernel I made that works with the card
is a 2.4.19-rc1 kernel from the linuxppc_2_4 tree.  This is the kernel
I was running for the lspci output.  I am also sending dmesg logs from
this kernel, and from a 2.4.19 kernel built from the linuxppc_2_4_devel
tree.  If they would be useful, I can also send diffs of any of the PCI
driver source code files between the two trees.  (I don't know how many
versions you might have laying around easily fed into diff.)

Ok, can you both try editing arch/ppc/kernel/pci.c, and in
pcibios_init(), replace the call to pcibios_assign_resource()
with a call to pci_assign_unassigned_resources() and tell me
what happens ?
If the resulting kernel boots, please send me the dmesg log and
the lspci -vv output.

Unfortunately, with this change the kernel doesn't even boot, failing
very early on with the last messages on screen being:

openpic enter
openpic timer
openpic ext
openpic spurious
openpic exit
