Ask Slashdot:Trouble with Glide

Kevin Way is having trouble getting his Diamond Monster 3D to work properly under Linux. It's kind of a strange situation. Hit the link below to read his description and see if you can't help.

The following is from slashdot reader Kevin Way

I just purchased a Diamond Monster 3D (original), and promptly downloaded the latest glide drivers from ftp.3dfx.com, recompiled the test programs and found myself staring at the message

_GlideInitEnvironment: glide2x.dll expected Voodoo Graphics, none detected

despite the fact that detect shows

and /proc/pci shows

How do I get rid of this error, and get glide to work?
