Hi,

Just a little discussion before creating a PR: I have a PM 9600 (six PCI),
and I've noticed that when I boot, I see all of my cards (SCSI and three
ethernet), but when I don't do a cold boot, I only see one ethernet and
the SCSI card.

First: if I do a shutdown -r now, it shuts down completely, then hangs. If
I do a shutdown -h now, I get to the OF prompt and can type reset-all, and
it reboots and I get two of the four cards.

The two that don't show up are in two of the three leftmost slots (looking
at the machine from the front); the two that do show up are in the
rightmost (inside, upper) slots. I can't afford the downtime to test
moving them, but I'm guessing this has something to do with the PCI
bridge:

So does anyone want to play with this, or should I open a PR?
