How about using wine+rage to test? A driver should be capable of running it. Thats where intel usually fails on linux. On win ivb is fast enough. You can run open arena or quake live on it, but don't consider that a real test of current hardware. Heaven maybe, something more demanding should be tested. Basically rage uses so huge textures that running with shared memory could be optimized even more compared to dedicated gfx card. A bit sad that there will not be a linux executeable for it, but it is still opengl, no big deal to try.
Code:
winetricks xact_jun2010 directx9
then run it. dx9 is not speed critical for this game, has nothing to do with rendering.
