Uploaded to ubuntu-proposed.

Tormod, it would be helpful if you could update the description with
additional details that may be relevant for consideration.

** Description changed:

- Binary package hint: xscreensaver
+ [Impact]
+ Affects Savage devices; unknown if it affects all Savage users or just a subset.  Leads to a crash in mesa during X startup.
+ 
+ [Development]
+ As Meerkat has not yet opened but Lucid is frozen solid, this fix is not yet in a development release, but it has been committed to the Ubuntu-X git tree and so will be included in the development version once Meerkat opens and we do our first mesa upload.  It will also be included in mesa 7.8 so we'll get it when we merge that in.
+ 
+ [Patch]
+ Patch has been proposed in this bug, confirmed to solve the issue, and accepted into the upstream 7.8 mesa branch.
+ 
+ [Test Case]
+ Install latest -savage and mesa, and then make X start up.  Crash ensues.
+ 
+ [Regression Potential]
+ The code changes are specific to the -savage video driver, and as such can't cause regression for non-savage users.
+ 
+ I've not reviewed exactly what the init call does in this case but
+ typically they just zero out initial values.  So probably pretty low
+ regression risk.
+
