[Centos] i810/agpgart problem with X

Hi list,
This is my first post to this list so be kind... :)

I installed CentOS 3.3 on a Dell Optiplex GX110 over the weekend and found that
when I try to start X, I get a problem with loading the agpgart module which
causes X to crash out. I did a little poking around Red Hat's bugzilla for
RHEL3 and found the following bug:

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=132935

You can get the full details by reading the page but essentially the problem
exists in the default kernel in RHEL3U3 (and hence CentOS 3.3). Yesterday an
errata was issued to release a new kernel which supposedly fixes the problem.
Linkage is below:

As comfortable as I am with the shell, having my desktop able to run CentOS with
X Windows would be much nicer. ;)

I'd be interested to know if anyone else has had problems with i810 video cards
and CentOS 3.3 and any experiences you may have with trying to get them
working.
