Chipsets of the motherboard, or chipset of the card? Does the agp code still support that type of direct mapping for those cards, and could you point me to the place in the driver code where that is done? It looks like the latest linux agpgart_be.c only uses gatt tables, which seems to imply it doesnt do the "direct" mapping any more ?
