These symptoms sounds like the problem I've been having since upgrading from Intrepid 8.10 to Jaunty 9.04 (amd64) on a Lenovo X301 (2776) laptop. In the 24 hours since upgrading it has twice locked up the screen display, mouse pointer, and keyboard. /var/log/kern.log shows a kernel 'Oops' related to 'i915_gem_execbuffer' - might be a separate bug or different error for same problem?
