I can confirm this bug on a Thinkpad T400 (fresh Intrepid system). The symptoms are exactly as described above.
Enabling the proposed-updates repository did NOT fix the bug for me! The symptoms stay the same. I can resume from suspend when I deactivate all but one core before suspend, however the system freezes as soon as I enable the second core again.
(If I do the enabling on a console, the system does not hang until I switch back to X)

Also tried the updated graphics driver mentioned above.
