Is there any method to compile NVidia drivers with linux kernel 2.5.18?
When I begin to compile them, they write
"error This driver does not support 2.5.x development kernels!" Is there any solution to make it work?

There was a patch to nVidia's v.2880 drivers tested on kernel 2.5.15 posted on May 13 which you can find here:

Attached is a version forward ported for:

o linux kernel 2.5.19
o NVIDIA_kernel-1.0-2960

I'm running it on a Dell Inspiron 8000. Besides 2.5.19 being sluggish as hell and that the HDIO_SET_32BIT ioctl seem not to work, quake2 runs like hell ;)

Cheers,
