You'd have to fix your BIOS.  Do an acpidump and look at the ASL file it 
generates.  Then, search for the string _PRT.  You will see that each PCI bus 
has one of these child objects, except for the one that has the AGP bus.  You 
can try creating a _PRT for it perhaps.  If you send me your ASL I can maybe 
try to work up a patch for it that you can try.
