** Description changed:

  For some days now, my acer 1362LMI (sempron 2800+) can start with the
  via driver for K8M800.(xserver-xorg-driver-via 33.2 ubuntu4)
  
  However most of the application using opengl (mesa) freeze the computer . This is the case with :
  egoboo
  tuxracer
  some screen savers
  torcs
  
  openuniverse and xcompmgr/transset are ok.
  
  I configured the video with dpkg reconfigure xserver-xorg with or
  without framebuffer, and I chose 16bits as color depth. I tested two
  kernels 2.6.15.21-i386 and 2.6.15.22-k7 with the same result.
  
  glxgears yields around 700 FPS (16bits + Kernel K7)
  
  I can play dvd smoothly
