Neat! What's left to do, and what's the schedule for integration?

Left to do:
a) Audit the device tree and correct any errors and omissions.
b) Release an Open Firmware version that uses virtual addressing so that
Linux doesn't clobber it upon startup. The coding is already done, so
this is just a release and test step. This version is compatible with
existing kernels so its release doesn't require a simultaneous release
of a new kernel.
c) Decide whether or not we want to go ahead with the /proc/device-tree
version, or convert to /sys first. If the latter, we have to develop
the sysfs version of the code. I think I understand how to convert to
sysfs for the bulk of the code, but there is still an issue that I don't
grok, namely the kobjects tie-in.
d) Do the administrative mechanics of expressing the changes as a patch.
e) Start converting OLPC userland code to use the device tree info
instead of the various ad-hoc detections schemes currently in place.
f) Do whatever needs to be done to announce the patch, submit it
upstream, or whatever we want to do on that front.
