Matrox g400 patch for hw blends / compositions

[Jaymz Julian]

Hi.  I updated my system to 2.6, and the mga driver stopped crashing, and so
I tried your patch.  Unfortunatnly, I couldn't get it to function correctly in
any state.

All of these tests are on a g400max, and probably may or may not be your
fault.

In 32bpp mode, the screen gets horrifically corrupted when you start the 
composite manager.  I suppose this is expected by your 16bpp comment belone, but
it would nice if it worked in that mode :).

In 16bpp mode, things somewhat work, at least a pure xterm does.  Starting KDE
exposed a whole pile of problems tho, specifically relating to colour corruption
(my black menu items and konsole turned flouresent green. for example.  
interesting, white text on black works fine, but black text on white came out in
various shades of green).

transparent windows did seem to work well, except for the aforementioned turning
some colours green, but that was expected from the above :).

fdclock in RGBA mode came out as a horrific corrupted mess, did it work for you?
