You could also have given ddcxinfo-knoppix a go. Sweet way to get your
modes for your xorg.conf. I can't remember / don't think it works with
LCD's though.

Brilliant! I pulled out my trusty Knoppix 5.1.1 CD and copied over
the resulting xorg.conf file - it is working like a champ now!
Next time you are in the RTP area, give me call - I'll buy you lunch :>
As an aside, 300 is the model, it is actually a 2x800MHz PIII, so
despite
being 7 years old, it makes a very usable desktop. My wife was using
an identical machine for web/email on Fedora 4 until recently. I'll be
using this one as a server, but having a GUI during setup and testing
is very handy.

For the archives: the Dell Poweredge 300 has ATI 3D Rage IIC AGP
graphics
and works great at 1024x768 with CentOS 5, once the xorg.conf file from
Knoppix 5.1.1 is moved over.
