Do they sell the DIMM module seperately, and if so, do they provide a
pinout if other people want to use it?

I'd be careful, the DM9000 design guides say something huge (iirc, 100uF)
for the regulator out decoupling, but this may be overkill for the worst
case. It may be there's some decoupling nearer the magnetics than the
DM9000. There could be other layout issues involved with the ethernet.

WRT to the watchdog, I belive the watchdog should generate an internal
reset to reboot the device, so it would be interesting to find out why
it isn't working.
