Hmm - this is strange. You are the second one to mention a segfault
right after starting - maybe something broke in CVS ?

That should work as a charm. However you should definitely _not_ use the
SVGAlib driver. The Matrox cards are nicely supported by either the kernel
fbcon device, or the kgicon module.

No. Though I suppose SVGAlib is the source of your problems. I do not have
any data on what works with it, and what not, but if you have a better
alternative, you should never use SVGAlib.
The library you are talking about is our SVGAlib wrapper. And it is kind
of a drop-in replacement, but not in the sense that you probably expect:
It will redirect SVGAlib programs to use LibGGI. If you install it without
having an alternate driver in place, that is useable from LibGGI, you won't
gain anything.
LibGGI itself does not drive hardware. It just uses a bunch of existing
systems to do that. SVGAlib is the "last resort" option for this.
Please configure the kernel fbcon device for your Millenium or use the
KGIcon driver.
For starters, you can also simply start up X and run the GGI programs
in a window.
