Bug description:
  [Impact]
  System hang with openchrome driver when using GIMP.

  [Development Fix]
  The issue was fixed upstream with a pair of patches.  An svn snapshot 
containing both fixes is shipped in Precise.

  [Stable Fix]
  The two fixes are cherrypicked and apply directly to oneiric's source.  I had 
to reformat the patches but there were no code changes required.

  [Text Case]
  1.  Boot up on an openchrome (VIA) based system
  2.  Start GIMP
  3.  Create a new picture
  4.  Move mouse cursor inside the picture
  Broken Behavior:  X.org hangs
  Fixed Behavior:  No hang, GIMP works normally

  [Regression Potential]
  The patches have received testing in Debian and upstream, so presumably 
should be fairly safe.  The number of people using openchrome is relatively 
small compared to the main X drivers, so the scope of risk is rather small here.

  The computer is a HP t5545 (a thinclient) and Jaunty is serverd to it
  through ltsp.

  It is 7:th of August 2009, the system is fully upgraded.

  In Jaunty:
  1. Everything works almost perfectly until Gimp is started and a new picture 
is created and the mouse cursor is moved inside of it. Then the whole X.org 
system hangs. It is possible for some time to log in through SSH but after some 
time the system locks up completely. "NoAccel" is solving the problem but the 
computer is then unacceptable slow. Same problem appears sometimes with Wine.

  2. A lot of green lines appears on the screen if I switch to a text
  console with Ctrl+Alt+F1 and then back to X (Ctrl+Alt+F7). By
  upgrading to the driver from Karmic, this problem disappears. But
  still this is not solving my first bug.

  In Hardy:
  The Via driver is not working at all with this computer.

  In Intrepid:
  The Via driver is not working at all with this computer.
