Ok

mga_vid is totaly unrelated to X. It actualy may interfere with it
in some cases as both directly access the graphics card.

I do not quite get what you see. Could you elaborate it a little bit ?

And could you also tell me whether you run mga_vid_test on a (framebuffer)

to test the code for it for quite a long time.
