PCI PowerMacs *do* have OpenFirmware - Apple had to impliment OF for PCI
support.

OF is how LinuxPPC works - MkLinux uses a booter like NetBSD, but LinuxPPC
does NOT need the MacOS at all to boot (and it only works on PCI PowerMacs
of course).  You have to break into OF early at startup and change some
variables at the command line to boot into LinuxPPC.  No reason why NetBSD
PPC couldn't do the same.
