Not true. The -current driver is indeed a port of an older version of the
FreeBSD driver, but it works fine with 789x chips. The only thing it
doesn't do is Ultra-160 mode. For that a newer version need to be
ported. This shouldn't be too hard, since the driver was reshuffled
to have OS-specific backends. Someone needs to just do it.
