Okay. I'm shooting in the dark, somewhat. I don't really have any
PREP/CHRP hardware - I'm just going off of some random lspci outputs I
have found with Google. I do know, however, that the PREP PCI host
bridge is incorrect in Pearpc, Qemu and OpenHackWare.
Does anyone have a Linux 2.6 /sys tree for PREP and CHRP? That would be
most useful for getting all the ISA, PCI and other devices correct.

I'm a bit confused. I closely reviewed the patch prior to sending and I
didn't notice any instances of whitespace-only diff. There are,
however, many lines of spelling changes. :) controler -> controller,
recurs -> recurse, to -> too, etc..

I'll look for it.
