This is not the real panic(), the real one is an assertion failure in
vm_page_wire().  In -CURRENT, vm_page_wire() should be called with the
page queue mutex held.  The nVidia driver lacks a fair amount of
vm_page_lock_queues() calls, and I wouldn't be surprised if it was
missing more things, with respect to locking.
