I've found out that it seems that with the newer Redhat 8.0 kernel, with a successful rpm rebuild of the kernel source, it says it can't find the NVdriver and X-Windows won't start.
However, using the SAME (updated RPM) package under 2.4.18-4 it works fine..
Even in regards to the above that I tried previously. For now I'm sitting on the old kernel.
Hurry up RedHat, migrate to 2.4.19!
