Devices that misreport the validity bit for word 93 look like SATA. If
they are on the blacklist then we must not test for SATA but assume 40 wire
in the 40 wire case (The TSSCorp reports 80 wire on SATA it seems!)

Alan, is this .24 material?
There were a lot of different threads and BZs about this one device, and
I want to triple-check that multiple fixes are not being applied
independently for the same problem.
