I didn't see patch 8/9, but the 'non-rotating' bit is in word 217 of the
inquiry data.  Unfortunately, Jeff insisted that we only report the
contents of that bit for devices claiming ATA-8 support, which is
ridiculous as even the Intel SSDs only claim conformance to ATA-7.

I notice that Jens was allowed to ignore Jeff's insane requirement and
doesn't have to check ATA revision at all.
