The rest of the code uses ata_ inlines/defines in ata.h for things like this
and religiously checks validity bits and ATA versions.

Feel free. I don't actually have a device like that here to test on,
so I'm not particularly motivated about doing more than the above right now.
Perhaps you or Albert may be, though. :)
That particular bit has always been zero (reserved), from ATA1 through present,
except when used as a DMADIR bit, beginning somewhere around ATA7.
