I'm running 2.4.19, and I enabled
Character devices->/dev/agpgart (AGP Support)->Generic SiS Support.

The README for Nvidia's driver doesn't say it supports SiS's
651 (I think that's my agp chipset).

It was set to 4mb, but I changed it to my video card's memory size(64mb),
and while it maybe have given me a few more fps, it didn't make agp
enabled.
