i could get it running with fbdev X driver, and i think mga +fb 
on a G550DH, but i needed Aivils hack for VT_SHIFT & 2 Xserver binaries

it's very, very spiteful :(

it's just that the maintainer doesn't like the new API,
and doesn't care much about the in kernel driver
and ....
he still ships his own matroxfb driver, which reverts the API 
change almost completely 
:(

but IMO this is the only (?i386?) hardware 
with some support for multi-head fbdev

best,
