M_NOWAIT can fail with NULL. Normally in an attach routine you should use a
blocking malloc (M_WAITOK) which will not fail with NULL.

At runtime you can use the devctl(8) command on HEAD (it will be included
in 10.3) to force a device to detach/attach to force a re-probe.
devctl detach mpr0
# note that the device won't be named mpr0, you will need to use its PCI
# location for this next:
devctl attach pci0:4:0:0
