Thanks Russell. 

    As a quick aside, I posted the same question twice because web archive does not show the email
content getting through:

    http://lists.infradead.org/pipermail/linux-arm-kernel/2010-December/035978.html

If no one with more experience in this area steps up, I can do some work on this, but I would need
considerable hand holding since I have not been following the names of these major subsystems within
the kernel as of late. 

Let's wait, and then I may have to raise the issue again if no one steps up.
