Ouch. That means we'll have to build our own kernel, and even with a
manual procedure (inside a specially prepared chroot). The reason we
were still using the /sys/class/net/eth0/lbs_mesh hack was that we
didn't want to fork the upstream (OLPC) kernel. Kernel updates usually
have a good reason, so they should spread automatically to all systems
in the field.

Maybe we should consider something like modifying the initrd
(initramfs?) from within some script in olpc-os-builder. Append the
module config file to the existing, already installed initrd. We'd also
need to add in some hook that runs when the kernel RPM gets updated
(which, I assume, means that the initrd gets replaced as well) so that
live updates retain our modification.
