Gordon, you are in luck, this was my situation exactly.
Go to matrox.com, find their drivers section, and download their linux
driver. It should be one file. Be sure to take a look at their readme,
it is good enough to get you installed. (except for the bit about groups
and DRI.... don't bother with setting a group for DRI.)
You will need a recent kernel. I use 2.4.0-test7. I built my kernel with
agpgart and mga modules available. They may or may not be needed. I'd bet
agpgart is required, mga isn't. <shrug>
There are two ways of getting Matrox's mga_drv.o into use -- replace
XFree86's version in /usr/X11R6/lib/modules/drivers/ with matrox's
(clunky, will get overwritten with each new xf86 upgrade unless you use
dpkg diversions...) -or- (the recommended way) is to use a direct path
in your /etc/X11/XF86Config-4 file to load the new module. I haven't
gone this route (lazy) but suggest you do. Sadly, I don't know the
syntax for this, so I suggest you look for all of Branden's postings in
the archives for more information about this. (Perhaps he mentioned it
in a thread with someone from nvidia...)
Once things are in place, modprobe agpgart, modprobe mga, and startx.
I have attached my XF86Config file for reference...
