is the fixed driver in sid? debian wheezy backports? Also, if its really
unusable in wheezy, the SRM will be happy to take a non invasive fix.
The driver was already fixed when the Wheezy freeze started. It simply never was granted a freeze exception.
Given this, what's in Testing could easily be backported as-is.
What's in Stable is usable, but rendering will fail in specific circumstances. Producing a cherry-picked SRM fix would be somewhat involved since a major whitespace cleanup was made just before the package was released upstream.
