Just a FYI: this still doesn't work with latest SVN 
Qemu/OpenBIOS/coreboot-v3 on x86_64. By adding some debug output in 
drivers/pci.c, I can see that io_base is now set to 0x1400 which must 
now clash with something else in Qemu.

Unfortunately I think that the reason I initially reported this worked 
was due to a local merge which I didn't notice in my local copy. 
However, I can get this to boot if I change the following line in 
drivers/pci.c from:

io_base = arch->io_base + 0x400;

to:

io_base = arch->io_base;

This drops io_base back down to 0x1000 and this seems good enough to 
allow Qemu to boot. So if this is required for PPC, perhaps one of the 
addresses in either the x86/PPC PCI address structure is wrong?


ATB,

Mark.
