The driver does send the command to the controller to do a rebuild if
DTWE_SHUTDOWN_NOTIFICATION is defined and an unclean shutdown happens.
It also continues the rebuilding process if it has been started, which
the openbsd driver does not do. In freebsd, I can just yank a failed
drive and put in a new one, and it will rebuild. In openbsd I have to
yank the drive, replace it, go into the 3ware bios, start a rebuild,
then boot off of a knoppix cd and wait for the array to finish
rebuilding, then reboot back into openbsd.
