Maybe, but your are just talking about abstracting what GPIO pins are  
used, which is a minor issue.

Grab a git kernel from kernel.org/git, I'd say to use either linux/ 
kernel/git/torvalds/linux-2.6.git (Linus's tree) or linux/kernel/git/ 
paulus/powerpc.git (Paul's tree).

You'd send the patches to me as I'm the maintainer for 83xx stuff.
