[ glxinfo OpenGL Extensions output trimmed ]

I realize I am not running the latest X, nor the Xorg X, but I have not
noticed any significant changes to MGA since the version included in
FreeBSD 5.2.1's DRM and XFree86 4.3.0's DRI.  I have not seen any
commits to the MGA drivers since the last update of this bug.  Has there
been any progress on diagnosing this issue?  I have the same "Idle timed
out" messages as the originator of this bug.  OpenGL applications are
unusable on my Matrox G200 due to this bug.  I would very much like to
resolve this issue without buying a new video card.  I am willing to
spend some time on it.  If there has been no progress, how can I help?
  
I am going to try running the glean suite on my system and will report
back whether or not it succeeds and where it fails if I can obtain that
information.
  
Thanks,
  
Brandon D. Valentine
