So that's probably the bug to focus time on, rather than the issue when
Have you tried disabling compiz (e.g. sudo chmod a-x /usr/bin/compiz)?

Have you confirmed that running trunk and EXA works for you?

There is not much time left. We may be able to pull in individual
patches. The current git of -intel (and thus the next release) require
an unreleased git version of libdrm; pulling git versions of both the
driver and libdrm brings a very large load of risk, so would require a
very strong justification to do something like that.

Do you have proof that other new intel cards are not booting ubuntu?
All my intel hardware is booting Ubuntu okay.
