Care to send a log ? I fail to see where the problem is since the patch

Or is that broken in some way ?

I'm starting to regret trying to use weak stuff :-) I may turn it into a good

#ifndef pcibios_fixup_cardbus
static inline void pcibios_fixup_cardbus(struct pci_bus *bus) { }
#define pcibios_fixup_cardbus

In a header and have ppc define it.

(And call it pcibios_ instead of pci_ which matches better what other arch
fixups are called :-)
