Okay, and there we are stuck with whatever the Kconfig name is. (we could 
rename that but not needed really)

Why not the canonical config_pci_bios() variant? It's the shortest one to 
write. The '_is' looks pretty superfluous to me.

Hm, i guess it could be mixed up with a function that configures the pci_bios.

I guess since i don't have any better idea config_is_pci_bios() sounds like a 
good choice after all.

Thanks,
