Just came across this:
http://www.linuxdevices.com/news/NS9508323422.html

An Open design robotics/educational Linux-based board with FPGA called
Qwerk from CMU. ARM9, 32Mb ram, 8Mb flash so doesn't have quite as
much gumption as ours, but it does have ethernet and the moter
controllers and poewr supplies are built-in.

Did you know about this lot Peter? Looks fun.
