The 7895 isn't a 789x.  At least, the BSD/OS driver, which does *NOT* support
the 7890, works fine on it, by probing it as if it were two 7880's.  It's
not an ultra 2, it's a dual-channel.

The 7895 is really just a 3940 on a motherboard.

(And I think Adaptec should be shot for giving it a number that looks like
a 789x.)
