I suspect what this refers to is the bug in the video driver for
the onboard video. If you don't have the patch to fix it, the
video won't actually work every time, and you'll usually have to
reboot the machine several times using cmd-ctrl-power until you
get lucky and the video driver works properly. Obviously, you
also have to either hold down cmd-opt-O-F each time, or change
the settings so it drops into OF by default. I'm not sure if that
bug would affect displaying to a PCI card.
