already done and queued for 2.6.39.  It may not be in it's final form,
and I'll possibly change the name, but take a look at the bgpio_chip
patches that were circulated on the list, and will be in my gpio/next

That said, I don't mind moving stuff into drivers/gpio first and
consolidating it after.
