You managed to get some LPC2106es? Wow, they're like rocking horse 
droppings around here in the UK!

/me tries again to get a response out of Avnet-Silica...

The bridge rectifier on the input is all well and good, but it means 
that any other boards running with this one ought to take power off of 
it, since ground will be a diode drop away. A single diode on the input 
rail, acting as reverse voltage protection rather than reverse voltage 
correction, is what I'd do.

Mmmm, kitchen sink boards... If I had money right now I'd buy one off of 
you :-)

Here's the schematic of the Olimex board, which is apparently working 
fine because they're selling it, in case you want to sanity-check that 
all the necessary lines are pulled up or down and that the capacitors 
and resistors are the right sizes:

Although they've got a bridge regulator on the input, too!
