Turns out that you are right on the issue of not working with the 2.6 series.
But the reason why it wouldn't load the module on my system had to do with the
fact that the version number was incorrect in include/linux/version.h and that I
didn't use the gcc version my kernel was compiled with. Now I have a module that
loads but that's no use. It seems to work correctly upto showing the following:

Matrox MGA G200/G400/G450/G550 YUV Video interface v2.01 (c) Aaron Holtzman & A'rpi
mga_vid: Found MGA G400/G450 at 0000:01:00.0
mga_vid: MMIO at 0xe0d18000 framebuffer: 0xE2000000
mga_vid: OPTION word: 0x400A1160  mem: 0x04  SDRAM
mga_vid: detected RAMSIZE is 16 MB
mga_vid: 1 supported cards found
mga_vid: using major: 83 (assigned or default!)

My /dev/mga_vid shows the following:
crw-r--r--  1 root root 83, 0 Oct 10 19:37 /dev/mga_vid

so everything should work if i'm not mistaken.

Anybody any ideas?
