When you try to resume, does pressing the caps lock key toggle the led? Can you press CTRL-SHIFT-ALT-F1 then CTRL-ALT-DEL and have the machine reboot? If so then this may be a duplicate of bug #594885. Please test the latest daily kernel build from the kernel ppa, or wait for Maverick Alpha 2 and report if the issue has been resolved.
