A nouveau hacker recently explained to me that it's fairly hard to
backport their improvements to older kernels as they heavily depend on
infrastructure changes. That likely explains why you don't see many
stable fixes or a nouveau-compat package.

If you can live with the nvidia driver, I can share a patch that makes
it build&work for me (Quadro FX 880M).
