sys/dev/pci : agp.c agp_amd.c agp_i810.c agpvar.h
Log message:
Don't map all agp memory we allocate.
If we're just going to be making it available to userland (the X
server), just use load_raw and make sure it's zeroed with BUS_DMA_ZERO.
Should save $AMOUNT_BOUND_TO_GART kva. Most kernel users also write
through the gart, so no mapping there either.
tested by sthen and todd a while back.
