I used a couple of G400s which were far past their use-by dates and 
spent a good deal of effort keeping them going.  The alternate 1.9.100 
branch of the mga driver was better.  It needs patches to build with the 
current xorg, which I have, but also there are reports of problems after 
that.  Haven't worked on it because I replaced the cards and retired the 
systems they were in.  The equipment is still available, and I may work 
on it again sometime.  My page with information:

The patches to remove cfb code from 1.9.100 are in that directory now, 
too, so they don't get lost.

You might also try the 1.4.11 version of the driver.  I don't know if 
it's a drop-in replacement for the 1.4.10 in ports, or if it supports 
your G550:

If your hardware allows (PC98 and sparc apparently don't), replacing the 
Matrox with a Radeon makes things much easier.
