An unkillable process is almost certainly hung in a driver, and in
this case I would strongly suspect it is a video driver.  Can you
break to KDB (or get a dump) and get a ps listing and a traceback
of the hung process?  That may enable someone familiar with the
particular driver involved to debug it.
