Here's the video of the boot up sequence:

You can see the odd PMU errors that pop up during the boot.
I watched the video, and it looks like the ADB stuff is working fine. If
I'm reading via-pmu68k.c correctly, those other pmu messages mean that
it's gotten a message from the PMU chip that it doesn't know how to
handle.
I think the "pmu intr 00" messages might be significant. My PB 190cs
prints that only once (see below) but ADB works (I was able to use the
keyboard to log in and I tested the trackpad with gpm). I noticed that
pmu_restart() works but pmu_read_pram() does not.
This kernel is kernel.org version 2.6.26.2. It has the macscsi lockup bug,
of course, but that bug somehow failed to manifest in both J's video and
the bootup in the log below.

The driver only looks like it handles the keyboard, trackpad, the extra
buttons outside the keyboard, and the regular heartbeat. For anything
else, it just prints out the data from the message. It looks like
nothing went wrong at all with the PMU. I see there's an error from the
SCSI port and obviously the lack of a root filesystem. Things actually
look fine, although I can imagine that the PMU driver is very sensitive
to exact timing.
