Per a conversation I have had with an Intel BIOS engineer it was pointed
out to you some time ago that the way you are doing all your own PCI
probing is not to the SPEC.  To do things correctly you *must* call the
PCI 32 bit bios hooks or we are going to continue to have this problem
and other problems as PCI evolves.  These are protected mode safe BIOS
calls and there is no good reason to not use them!
