I'm using the COM port on my PC (yes, it has a real one!) to do things
to my rb-2011uias-2hnd.  It took me w while to produce a correctly
wired DB-9 to RJ-45 cable but I managed in the end.

By 'uboot' do you mean the ability to change boot source etc. by
hitting a key on reboot?  This is what I'm doing to load openwrite.
Reboot the rb-2011uias-2hnd, hit a key on the serial port and then
tell it to boot from ethernet using tftp.  It's pretty
straightforward.

I can probably submit a patch for mach-rb2011.c parallelling the above
one this week-end.
