flashdevice.sub has at best dubious value to start with.  There are
literally thousands of geometries that we'd need to support.  In
addition, this is a highly OEM'd business, so today's flash with a
'SanDisk 512MB' label won't necessarily be the same one in 3 months,
when a new process comes along.  Having had to buy CF for a commercial
application for the past 5 years, I can tell you that every single one
of the 'lots' that we've purchased has been different.  Even when
we're assured by the supplier they will be identical.
