Not that much actually. Look at pmac, I have nothing even close to
the 0..15 ISA namespace. Of course, a few crappy legacy ISA drivers
are broken, but we don't use them on PMAC, and you can eventually
hack them if you need them on embedded until a proper fix gets done.

BTW. At least serial.c is beeing redesigned by Russel King (ARM) ;)
