   Sounds like it might be the same as PR 7473... the kernel crashes if you
   close a USB mouse that has been disconnected.

Just a quick note....

On obvious workaround that I use is to exit X first and then unplug the
mouse.  This seems to yield a reasonable result.  I also found the XInput
extension and the 'xsetpointer' useful [X on the i386 plateform only,
perhaps, others may vary].  With that you can define a second mouse and
switch to it simply.  Not quite automatic, but I haven't seen crashes and
the Logitech USB mouse I have for my notebook is pretty nice.
