Description of problem:

Steps to Reproduce:
1. startx (only KDE is installed, do not know what happens with Gnome)

Disable the RENDER extension in your config file. Render isn't supported
on i810. This means no AA fonts in KDE also, so make sure AA fonts are
disabled. The missing symbol errors have been fixed already in
XFree86-4.0.3-21 which will be released shortly on my test site.
Does the problem go away if you run "modprobe agpgart" as root prior
to starting X?
It appears that this might also be a CMOS misconfiguration problem.
Others have reported i810/815 bugs have went away after correcting
bad settings for memory in their CMOS configuration.
This bug is a dupe. Please update the dupe report with any info. I'll add
you to the Cc.
