2.6.4/i810/AGP GART issue

[snifflesthor@hotmail.com (Tim)]

I've recently upgraded from 2.4.25 to 2.6.4 via a source from
kernel.org. I'm
having the somewhat common problem with my x server. The message is:

"Unable to open /dev/agpgart (No such file or directory.)
AGP GART is not available..."

After 10 kenel recompiles and countless searches, no progress so far.
I've switched on every conceivably related module. I still cannot tell
if this is a kernel-related problem or if x is simply not loading the
proper module(s).

Has anyone actually solved this? 

Thanks,

Tim
