agpgart for P4M266

agpgart for P4M266

Hello,

Below is a patch to 2.4.21-rc6 that adds agpgart support for Via Apollo 
P4M266. This chipset is used by my EliteGroup P4VMM2 mainboard. It works
fine on my machine, e.g. I am able to run Quake III Arena and it runs more
smoothly after the patch was applied. I was only able to test on my
machine which has an NVIDIA TNT2 based gfx card (using drivers from
NVIDIA).

Please CC me when replying as I am currently not subscribed to the list.
