Thanks for the testing feedback so far. This release fixes a couple of
major issues.

Notable changes:
 - Fixed bug where olpc-update was not working and could even break
your system on next boot. Sorry about that. Users of build 20 and
build 21 will have to reflash this image directly, rather than using
olpc-update.
 - Fixed a bug introduced in build 21 where XO-1.5 wireless hardware
was being reset on every resume
