That sounds like a fine plan.  If you'd like, you can submit both at
the same time (as separate patches).  More board ports are always
welcome, particularly for stock eval boards.

Preferably, you'd submit to the tip of the git tree for 4xx.  With the
pace of kernel development, releasing patches for "old" kernels just
means that someone has to forward port them to the latest tree.  That
might be a small effort, but in practice it's best to work with
bleeding edge if you're going to submit a patch for inclusion.

Don't be discouraged by that.  There are those that will help you if
you run into obstacles.

The easiest place to start is Documentation/SubmittingPatches in the
kernel tree.
