Thanks for explanation. So it seems for making such job easier it is
better on i386 to keep current way of doing PCI init and call pcib_init
from the elnk driver. Personally I think it would be good to at least keep
things in the same way on the same architecture.

If you agree, I'm going to make appropriate code changes myself.

Thanks,
Karel
