Yep -- it's specifically an issue with the 4965, and can be a problem for the 3945. That's in the "Other Known Issues" at http://www.ubuntu.com/getubuntu/releasenotes/810.
Here is what's working for me: I removed every backport, but I didn't purge them. Then I commented out all by the 2.6.27-7-generic kernel in my /boot/grub/menu.lst. That kernel, at least in my case, doesn't have any hard locks. I know the backports module is supposed to take care of the hard locks, but it also kills my wireless; with the backports installed, no networks show up in NetworkManager, and when I try to modprobe it, it spits an error. So the fix introduces another problem -- wireless can't lock up your machine if it doesn't work, can it. Sort of like burning the village to save it. -- (COMPIZ ???)
