Re: Access to PCI Expansion ROMs on PPC

You can dump the PCI config block in /sys with hexdump and see if the
PCI_COMMAND_MEMORY bit is set. I was also unable to locate where in
the kernel PCI_COMMAND_MEMORY is being set. It could be that it is set
by the BIOS at boot on the x86 and not on the ppc.

The kernel doesn't until somebody calls pci_enable_device(). So yes,
that's likely to be your problem.
