Subject[PATCH] [2.4] AGPGART support for intel 7205/7505 chipsets

please Cc:, I'm not subscribed to the list.

Attached is a small backport from 2.6 to 2.4 to add support for Intel's
7205 and 7505 chipsets. The patch has been tested and works using
NVIDIA's binary-only drivers with a GeForce 4200 in AGP 8x mode. We
haven't been able to get a Radeon card to work yet. The last version
of the kernel that I've used for testing is 2.4.22-pre6-ac1.

The machine where this has been tested has 4 GB of RAM installed and
the kernel sets up, right after booting, 8 MTRR regions leaving none
for the AGP aperture or the graphics card memory. In that situation
the NVIDIA driver fails to set up AGP properly and disables it
altogether. The last two regions look like this:

reg06: base=0x400000000 (16384MB), size=16384MB: write-back, count=1
reg07: base=0x800000000 (32768MB), size=32768MB: write-back, count=1

by disabling them and then starting the X server everything works fine.
