digest..."
olpc-3.10 has quite a few hardware problems on XO-1, to avoid those
problems drop down to x86-3.3 branch, which is what we use for builds
at the moment.
In olpc-os-builder the kernel comes from the yum repositories
configured in the .ini file, specific to the hardware model.
e.g. http://rpmdropbox.laptop.org/f18-xo1/
It doesn't know what git branch to use; that's the responsibility of
the OLPC kernel maintainer to choose where to upload an RPM.
See http://wiki.laptop.org/go/Kernel for details.
