11.3.1 development build 29 for XO-1.75

This build brings in OFW improvements, audio fixes, olpc-update,
ds-backup, powerd and new power logging scripts.

It should be updatable via olpc-update -- try the cmdline below.


 - In normal use, the laptop sometimes hangs when idle; very likely
when it is suspending or resuming; please help us diagnose this
further at #11600 and #11658

 - Record Activity will sometimes hang - #11657

 - The getty on the serial port is _disabled_ by default now (that's
the workaround). It gets enabled when you hold the "check" game key
during boot (for verbose boot).

Upgrade online with:

   olpc-update 11.3.1_xo1.75-28

Download from:


Fixes (please help us confirm):

#11664 olpc-update-query has a hardcoded /ofw path
#11665 olpc-update needs to learn about devicetree
#11667 Teach ds-backup about devicetree
#11623 Add olpc-pwr-log Ver 2.1.0 to build
