Greg,
I'm getting the following message from the kernel on an embedded ppc32 
system:
PCI: Failed to allocate mem resource #9:100000@e0000000 for 0000:00:00.0
The HW setup is a PCIe host controller and an e1000 NIC card.  It 
appears that pci_bus_assign_resources() is trying to call 
pci_assign_resource() for the ROM and the resource for the ROM is 
[100000:1fffff] where the PHB is [c0000000:dfffffff].
It seems like the resno that pci_assign_resource is getting called with 
is wrong and thus pci_update_resource() doesn't get called.
any ideas?

Kernel version, please.

Sorry, its 2.6.24-rc7 + some ppc patches queued for 2.6.25

Could you try this patch?
http://git.kernel.org/?p=linux/kernel/git/gregkh/patches.git;a=blob_plain;f=pci/pci-remove-default-pci-expansion-rom-memory-allocation.patch

Greg: is this 2.6.25 material, please? We need this for SP2.

Yes, this is queued up for 2.6.25, and I have no objection to adding it
for SLE10 SP2 if needed.  But I think there is another patch in the
series that also goes with this, ask IBM, they know what is needed here.

thanks,
