Thanks, I was fairly proud of my efforts and if I did infact own a 3Dfx card I 
would instead be on here raving about the ease of install :), as I really did 
nothing to 'setup' glide, it just kinda happened :)

I believe Nvidia doesn't use DRI anymore, as I found out when my friend and I 
got Quake 3 running under FreeBSD on his machine(Nvidia card), but that's not 
important, go on...

Ok, Radeon and Agpgart installed and working correctly here.

Xfree is setup as you described it, and when i run glxinfo it reports Direct 
Rendering: Yes and a HEAP of gl extensions, glxgears runs at around 1500fps, 
which i'm told should run at around 300 without OpenGL acceleration, so I 
think it's safe to assume that BSD DRI is operational, the problem comes when 
I try to run a linux binary, I have all the compatibility installed and the 
linux-mesa port but unfortunatly the linux compatibility libGL.so.1 thinks I 
have a GLIDE based card and blindly loads GLIDE.  Of course it fails straight 
away.

It was extremely helpful Paul, as I used it as a checklist to make sure that I 
had followed the right path, but now the fun begins as I suspect it's the 
linux version of libGL that's detecting GLIDE, and not FreeBSD's native 
libGL.so.1.

Any more insight will be most appreciated, and thanks for the effort you'v put 
in so far.

Cheers,
