That said, yeah, it probably would be a good idea to add a

How about some form of auto-detection instead?

That's a device which reports that it's a PMP but fails to behave
itself as one. The sucky thing is that depending on the current mode
and firmware revision, the same hardware can actually bahave as a
pretty decent PMP.

Yuck! :)

I suppose *if* we knew the exact fwrev that requires the workaround,
then we could make it automatic for that, and still have the boot flag
for cases we don't know about.

Tobias? Got the IDENTIFY info from that device?
Something like "hdparm --istdout /dev/sdX" ?
