Here is an updated patch to the binary-only drivers provided by NVIDIA
(version 1.0-3123) for kernel 2.5.40. I have tested it for both 2D and
3D and it seems to work fine. (Warcraft III under linux 2.5.40 should
be a good enough test, no?)
I have not tested their NVAGP under 2.5.40. If in doubt use the
kernel's agpgart driver and:
Option "NvAGP" "2"
to tell the NVIDIA driver not to use its internal NVAGP driver.
This patch is based on a patch previously posted by Roberto Nibali. I
place my contributions to this patch under the GPL. NVIDIA may not use
this code without prior written consent from me.
Cheers,
