Hi,

Well, why not?
jmicron class has the get_registers() method which fetches adapter
registers, and some ranges are known (0x720f, 0x8000, 0x9000).
Thus it's only a matter of adding a helper to dump the full register
space, then having some people with different JMicrons provide a dump,
then someone should have a hard look at it to figure out the revision
register, that's it.

BTW, owning a JMF601 (0x0601), and having a hell of a time with it...
I suspect it's SMART-capable (docs say so), but all analysis currently
was not successful yet - but I still have some tricks to try...
