For the latest debs I need to use at least 2.4.0-test9 for
hardware-accelerated OpenGL, and it only works with the stock XF4 mga 2D
driver (instead of the binary driver from Matrox).  Also, I am using 16
bpp, but I have seen reports that you can get it to work with 24 bpp if you
tell it to use 32 bpp internally.

Virtual consoles work fine for me whether or not I use kernel matroxfb.

Right.  This is why I was unable to use the binary driver from Matrox.  Try
using the stock driver that comes with the debs.  Unfortunately, however, I
am guessing that you won't be able to do dual-head in that case.
