FWIW I think this deserves even higher severity, it should definitely be
fixed for wheezy.

I think the attached patch should fix this. Can you or anyone else on
the debian-powerpc list test it?

BTW, if you spelled "RenderAccel" correctly, Option "MigrationHeuristic"
shouldn't be necessary to work around the problem. In theory the latter
won't avoid the problem in some cases anyway.
