Ahh, you weren't cc'd earlier, and may have missed the discussion. It's on 
Linux-kernel in the thread called "Oops/Warning report for the week of 
March 28th 2008"

Johannes says this triggers for him:

	On the other hand, it should be easily reproducible by anyone else with
	the same trick, here's what I do:
	
	 * configure X to use /dev/input/event* devices
	 * in an xterm, do something like
	      rmmod usbhid ; modprobe usbhid
	 * switch to a VT
	 * watch kernel crash as X releases the grab on the event device

and I haven't tried it because none of my normal machines use modules, and 
I was lazy and really hoping somebody else who actually knows the device 
and input layers would take a peek.
