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.
