same symptoms as previous 180.XX drivers on a sony vaio fz31m, 8400gt m:
deadlock after suspend, no wake-up, not even sys rq works. do not bother trying this out.
in my opinion this should be priority number one to fix suspend befor final release.
otherwise this is a half-driver.
the real issues are not being fixed, this is:
i am stucked with 177.XX, where from all those issues, just suspend works and reverting to 173 which once worked so well, does not work as with the newer kernel-release the 173-driver thinks the 2.6.27-11-generic kernel is a XEN kernel.
