I'm not an X.org expert, Alan Coopersmith, a primary maintainer/developer for OpenSolaris' X.org implementation would know the answers specific to support and this particular problem, if it's reproducible or fixed, etc. Might also want to check the OpenSolaris bugs database for GMA950-specific problems under X_WIN.
