OpenGL glxgears demo program

[Brian McKee]

Just a complete WAG here....

Are there a settings in the BIOS relating to your video?

I remember having issues with Intel i810.  In the BIOS there were two
different amounts of system ram it could use, and two sizes of (I'm
sure I have the terminology wrong) AGP cache or window.  Turning both
of them to their higher setting resolved the issue.

Figured it couldn't hurt to at least look.
