Yeah.. basically it's prep compliant when provided with PPCBUG firmware,
without it it is mostly-OFW compliant.
How to get.. not sure.. but I'm told you can basically flash it on from a

You're positive no residual? I've seen a few CHRP IBM machines that still
provided residual if you asked for it.

Yeah.. contact me off list about this. I'd be interested in seeing some PCI
dumps for the machine. One hint, my problem was that after I mapped the
openpic, the PCI_NETBSD_CONFIGURE option went behind my back and remapped it,
making it impossible to talk to anymore. So while it wired up fine, once that
ran it was toast.
