This is an unfortunate situation. There is a non-trivial number of users
with 845 and 855 chips who are impacted by a regressions in stability in
the current x stack when running 3d and KMS.

We have opted for a "stability first" approach for these users. We will
disable 3D and KMS for these chips in Lucid final release. This will
have the unfortunate effect of disabling compiz. This will introduce a
functional regression. So we will be sacrificing functionality for these
users in favor of stability. This is a painful choice to make, but we
feel that stability must trump functionality when we are forced to make
such choices.

We will be pursuing functional fixes. However, we will do this outside
the main release, for example in a PPA. If we are able to provide a fix
that delivers stability and functionality, we will consider this a
potential SRU in 10.04.1.
