Thanks for the suggestion; I didn't know about the ports version of the driver.
That version works! So perhaps all that's needed is to commit the ports driver
to base.

Interesting that the 12.0 driver has fewer sysctl knobs to turn. Also
interesting that the current base version of the driver does not print its
version number in the probe message.
