Unfortunately, it takes forever on this machine to compile a kernel
after any bigger changes. I can do it early next week when I have access
to my bigger box again.

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

Mind you, I actually did this with the appletouch driver, but I don't
think it makes a difference since the problematic thing is the code that
X grabs the device. A trivial program that executes the grab ioctl would
probably suffice if you leave it running over a rmmod/modprobe cycle.
