RADEON_DEBUG=fp log

The game ColorCube isn't working correctly when GLSL is used:

r300 FP: Compiler Error:
r500_fragprog_emit.c::emit_paired(): emit_alu: Too many instructions
Using a dummy shader instead.
r300 FP: Compiler Error:

This is most likely the same, or similar too bug 28860, as they are both built with the Blender Game Engine. 

Contrary to 28860 I don't get any "rejected CS" in this game.

It's a hardware limitation. Closing..
