I'm having a similar problem, the screen freezes an I can only manipulate the mouse curser. I can see that the curser still is context sensitive (changes to I-beam shape over text-fields etc), but there is no other response from X. Attaching to a different console (ctrl-alt-#) gives me only a black screen, but I can carefully log in blindly and get back into X by restarting the gdm service.
I can reliably reproduce the problem by starting DavMail Gateway and a mail client (tested with Thunderbird and Evolutuion). If I mouse over the DavMail client icon in my status-bar, which would normally give me a status pop-up, the screen will freeze if not running in Classic without effects.
I'm running the 2.6.38-11 kernel and Ati Mobility radeon HD3650 with catalyst version 11.5.
