However, the Blue G3's and all G4's as well as the iBook and any other computer with AGP (including the "fake AGP" fast PCI slot on the blue G3's) have two PCI busses, since AGP is only a fast PCI bus (with a few enhancements, but as far as Linux is concerned, it's PCI). AGP slots will run compatible PCI cards at 66MHz (though there are certain keys which prevent insertion unless the card is compatible). A notable example is 3Dfx's Voodoo2 1000 card (and several other brands) which allow a 66 MHz bus. On a side note, does anyone know if Linux properly supports the 64-bit PCI slots in the Blue G3's and G4's? The only cards I know of that use them are several SCSI cards and TotalImpact cards.
