Well, MIPS has been looking at us a bit I know.  Also, the patch that
Mark/Matt did uses the pci_auto stuff for setting up the bridges (iirc
thats what that code is for anyhow :)) and MIPS has been using that
as well of late, tho their gt64120 bits don't look like they use it
right now.

If nothing else, yeah.  And all of the drivers into drivers/.
