CentOS - May 2007 - Can't get resolution higher than 1280x1024 - Centos 5

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:

What monitor do you have?

No, it should work just fine. you'll only get 2D support without the
proprietary driver from nvidia though.

You don't have the appropriate kernel-devel package installed (yum
install kernel-devel) and you'll want to install gcc also if you don't
have it already.

Yeah.. uh.. I uh might have to ask you to send me this hardware for
testing. Yeah, that's it... testing... you know.. to make sure it
works :-P

Right, and it should continue to work fine, but sometimes KVM's mess
with the real hardware detection, so the system will get confused and
put you at a lower resolution.

gcc.  ;(
Does the kernel-devel version match the kernel you're currently
running? Look at the output from 'rpm -q kernel-devel', and match the
version and release numbers against the output of 'uname -r'. If the
two are different, that's why the nvidia installer is bitching.
Usually this is caused by not rebooting after a kernel update.

Someone around here suggested ATrpms, which has been known to cause
some problems with people's systems. RPMForge has the nvidia packages
as well, and I'd recommend them over ATrpms for stability and generall
packaging sanity. That and Dag (and Dries too) have been known to
frequent our mailing lists and developer channels. I've never once
seen Axel (from ATrpms) offer assistance on the list or stop by irc to
see if everything's kosher.

You might also want to try a 'system-config-display --reconfigure'
from a console and see if you can't tell it just exactly what you've
got and what settings you want to use.
