I have a similar problem on Feisty... 30% of the time I resume from Suspend (to RAM), the keyboard and touchpad on my Inspiron 6400 are dead. Plugging in a USB keyboard and mouse lets me shut down.
Interestingly, sometimes I can suspend again (with the USB mouse), and the laptop's keyboard/touchpad work after resuming again. Not always, though. Sometimes it just locks up after the second resume.

So... this is still an issue?
