The specs of the g400-series adapters have been available for download
on the matrox site for a few years now.

IMO it's more a problem of not having enough people who have enough
experience to make the drivers perfect... it look like working on 3d
drivers required a lot of knowledge of 3d graphics and hardware
rendering pipelines.
The most recent open source 3d drivers (xfree ati r200) have not been
created by the community, but by paid professionals. After they quit
working on it only minor bugs have been fixed. The OpenGL display
quality and/or rendering speed have not really increased...
