Note that I think that a blacklisted drive should only _default_ to DMA
off. If somebody wants to take the chance (maybe the bug only occurs in
certain batches), we should allow him/her to turn DMA on if wanted.

I don't ant to baby-sit people, I just want us to default to a safe state.

I'm chasing down one SMP problem that apparently started triggering with
the (fixed) 2.1.112. It might be the lock, for all I know, but it's
interesting to note that the new lock code _should_ do the same thing as
the old one with the exception that the new code won't ever work with
interrupts trying to get the kernel lock (which is a no-no and has been
for a long time, but maybe there was something there still doing it).
