well first you don't put that snippet of code anywheres ..
that is a directory listing of eNTi's /usr/src folder ..
secondly the steps should have been as followed ...
1) upgrade kernel
2) boot to runlevel 3
3) navigate to folder containing nvidia installer
4) ./NVIDIA-installer.run --uninstall
5) ./NVIDIA-installer.run
6) should say they were successfully installled ...
7) startx
8) enjoy gui with 3d acceleration
now please people don't reply telling him "well its better to do this, and then this in stead of when ozz did this" ...
of course these steps can be rearranged ... but give the guy a break and let him try this .... for instance we know step 4 could actually be step 1 .. etc, etc, etc...
now i assume you updated to a 2.6.x series kernel .... if so, then i have a feeling i know what error your receiving but you didn't mention it to helps us help you ....
but in any case, with the steps above, and
THESE 2.6 modifed nvidia drivers ... you should be good to go
