Compiz Sandybridge blacklist is no longer needed.

Binary package hint: compiz

Previously, the device id's for the next generation intel GPU's that do not have functional 3D support were added to the blacklist in compiz on the assumption that partially working 3D support would be implemented by maverick's release, but that is not the case and DRI has been disabled completely for these devices so other 3D applications would not hang the system. The compiz blacklist is no longer needed in this case because the software rasterizer is used which is already blocked from using compiz. Leaving the blacklist in place would just be a maintenance burden, given that the fixes required to make 3D work may actually be SRU-able in the future and the blacklist would have to be dropped post release for people to use it.
