OpenGL-ES is designed to run on the ARM. That flavor of OpenGL
supports integer only operation. There are several OpenGL-ES stacks
for the ARM but none are free. Xgl should run on OpenGL-ES but it may
need some tweaks.

This one looks promising 
http://ogl-es.sourceforge.net/

I wouldn't expect that taking a desktop server and simply compiling it
for ARM is going to work very well.
