where might I find such documentation?
The 5v regulator is an LM2734 or 36 according to the schematic. That's rated at 1A and a switcher so it may be good at full tilt however the product page says 800mA on both 5v and 3v3 so one has to assume that's correct.

finally has decent supply for both voltage rails.
Thanks Rob. It's good to see a board that finally has decent supply for both voltage rails. I've always considered the feeble 3v3 supply on the 8-bit boards an annoying weakness in the design.
