Well, that's annoying!  :-)

I have some DM9102 boards on the way from Davicom, but they're apparently
stuck in customs!  Grumble.  Anyhow, I'll keep this in mind when adding
support for the chip.

Can you please point me at a datasheet for the ST201, and tell me which
card has it?  So far, Sundance hasn't responded to my requests for a
datasheet and demo board.
