good plan.  i recall someone saying that building a kernel on the XO
can literally take days.  :-)

get a copy of the olpc kernel source from dev.laptop.org -- look
for the source here:  http://dev.laptop.org/browser the project
is called "olpc-2.6".  there are instructions at the top of that
page on how to fetch from git.  when you fetch with git, you'll
want the "testing" branch.  i believe the 767 kernel is tagged,
but since all you'll be building are things that have almost
certainly not changed since we released, you could probably build
HEAD if you wished.  (i'm only "pretty sure" about that.) btw,
the git/web interface will also let you fetch a tarball if you
don't want to bother with git -- click on "tree" and "snapshot".

for bluetooth and the supporting USB driver modules there are no
kernel dependencies, so just building the modules would be
sufficient.

however, if you'd like to shortcut the whole process, you can
pick up the modules you probably need from:
    http://dev.laptop.org/~pgf/bluemod.tgz

i built those for my own use.  i'm not running the stock kernel anymore
for other reasons, but i believe those will load on 767.
