I have been testing nmahale's patch the last couple of days. It does indeed seem to have fixed the freezing.. However, in place of the freezing, I'm seeing the touchpad periodically stop responding to scroll and RMB clicks. This happens with extreme frequency. Usually once I start doing a scroll with two fingers, I can only scroll very briefly before the scrolling locks up. This tends to happen most frequently when cycling between windows.
I've tested booting to an ubuntu iso via usb, and the problem goes away. Things I've found that unfreeze the touchpad include toggling the touchpad off/on, either via key command (fn+F9 on my laptop) or via 'modprobe -r psmouse; modprobe psmouse', or hitting the enter key. This happens inside of all applications, including browsers and terminals. Not seeing anything useful in the logs. It's possible that this is an unrelated problem, but I've only been seeing it when running the patched xorg.
