I've compiled XF86-4.2.0 just a couple of days after
it was released, for Matrox G250 (almost the same to
G200) using MGA driver done by Matrox. It compiled and
linked fine, but whenever I ran X on fresh boot I
received a nice looking black screen, however when I
opened a window or two in AfterStep I could see window
headers, so I could catch them by mouse cursor, move
here and there to clean my desktop ;) Looks like a
problem with framebuffer flushing. Anyway, it was
boring to do it on every boot-up. So I recompiled X
again with built-in MGA driver, disabled HAL, set some
extra parameters manually in XF86Config to disable DRI
which didn't work anyway etc., it still runs fine at
24+8 ARGB colour depth.
