I have an AGP 3DLabs Permedia 2 card at home and it works fine -- the
XFree86 docs seem to suggest that if the card works under PCI then it
should work under AGP without any problems at all (from what I
understand it's definitely not a kernel problem).  I don't really
understand what the distinction is between PCI and AGP (apart from the
different physical interface) and cat'ting /proc/pci seems to indicate
that Linux treats AGP devices as if they were PCI... (I'm sure someone
else probably understands the subtlies of this than I.)
