Michael Larabel - btw Alpha-3 (due next week) would be a good candidate
to do performance testing/comparisons against, for -intel. We're
anticipating including the 2.8.0 driver in that, which fixes a bunch of
KMS issues and should largely solve the jaunty performance problems.
In fact even alpha-2 is a pretty solid advance for non-KMS cases and
should compare well against jaunty. Alpha-2 fixed a metric ton of
issues that had been reported against Jaunty, between the 2.6.30 kernel
and the updated X infrastructure (xserver+mesa+libdrm+-intel).
