I'm using that configuration currently with an R/C car-based robot, and
it seems to work fine -- I haven't fried anything yet. I did decide to
tack on a DC-DC converter and an extra couple of standard RC batteries
to power the gumstix and the various other electronics I have on board,
since I wanted a nice long run-time, but these run independently of the
system you're describing.
