Actually it turns out that most of these bugs aren't just FirePower specific,
but are more widely found on other Firmworks OpenFirmware implementations as
well.  While I do have a list of firmware bugs encountered, it isn't up to
date (I just installed a new version of the firmware last week), and it has
a lot of things unrelated to NetBSD/powerpc.  Apart from that there are a lot
of things in there that do make only sense if you have the same firmware
available.  Let me know (in private mail) if you really want/need that list.

See my other mail on this.

Depends on whether there are machines out there with some of those bugs...
