Hello all, I can't get higher than 1280x1024 resolution (60hz, 24 depth). 
I'm running Centos 5 x86 64bit on AMD Athlon64 x2 4600, Geforce 6200 PCI
express.  Even as root, that is the highest I can set the display.  I am
guessin the kernel does not support my combo?  I've also tried Nvidia's
driver from their site, this is what I get:

Using: nvidia-installer ncurses user interface
-> License accepted.
-> No precompiled kernel interface was found to match your kernel; would
you li
   ke the installer to attempt to download a kernel interface for your
kernel f
   rom the NVIDIA ftp site (ftp://download.nvidia.com)? (Answer: Yes)
-> No matching precompiled kernel interface was found on the NVIDIA ftp site;
   this means that the installer will need to compile a kernel interface for
   your kernel.

ERROR: Unable to find the kernel source tree for the currently running
kernel.
       Please make sure you have installed the kernel source files for your
       kernel and that they are properly configured; on Red Hat Linux
systems,
       for example, be sure you have the 'kernel-source' or 'kernel-devel'
RPM
       installed.  If you know the correct kernel source files are installed,
       you may specify the kernel source path with the '--kernel-source-path'
       command line option.

       '/var/log/nvidia-installer.log' for details.  You may find suggestions
       on fixing installation problems in the README available on the Linux
       driver download page at www.nvidia.com.
