Yes, that is a good idea. I would also suggest that you don't try to port
all the code at once a few kernel versions at a time, but that you instead
move straight to the latest kernel, and basically start a new port one driver
at a time. Take one of the newer ports (highbank, virt, bcm, ...) as examples.

Since most of the code is now in drivers/ directories rather than arch/arm,
you can actually start getting stuff upstream before you have completed all
of it. If you have questions, I recommend asking on the #armlinux channel
on freenode, or here on the mailing list.
