I pulled his tree and tried building on powerpc w/ gcc 4.3, it passed.

I'm not too excited about the extremely long open-coded variable
definitions everywhere now though. Wouldn't it be better to just do a
macro for it?

Something like:

#define PCI_DEVICE_TABLE(_var) static const struct pci_device_id _var[] __devinitconst

And then just:

PCI_DEVICE_TABLE(mydevice_tbl) = {
	...
};
