Just fire up the X server with EXA and start compiz, basically.

It's stable IME, although slow, but that shouldn't matter for this.
YMMV.
Anyway, Shawn said on IRC:
oh, and EXA causes X server to die when compiz is started :)
which matches my expected failure mode of this patch: it tries to
reference XAA symbols, which are unresolved because XAA isn't loaded, so
the X server is aborted immediately.

Well, I'm not aware of any changes since the last release candidate that
would affect this...
