The patch in question should just be reverted for 3.3.1-stable. It would mean
that power-saving would take a hit on that kernel - but it's impact would be
much lesser than a broken driver, one that fails in basic connection.
I'll send a patch reverting c1afdaff90538ef085b756454f12b29575411214.

For 3.4, can you build the driver with debugging enabled [1] , load the driver
with debug=0x801 and post the log here (before/after resume) ?

Thanks.
