It still affects my system... in about two hours, my 4Gb are entirely filled (but not by any process, memory is just lost) and swap start to fill... when that happen iowait grows to 90% more and render the system unresponsive. That does not happen with the free open source radeon driver, only with the proprietary fglrx. But since compiz works now with the radeon driver and my ati 4650, it's not so much of a problem...
