Ah.  So an easy accommodation is to declare a 360RPM 1.2MB drive as a 
1.44MB 3.5".  That keeps the 250Kbps data rate for low density while 
the drive keeps spinning happily at 360 RPM.  There's still the issue 
of the missing IAM gap, but some National chips (8473 IIRC) seem to 
be a bit more tolerant.
