I have a PC keyboard, and tried windows-alt-p-r. According to Apple
documentation, I should hear 2 beeps, but I don't, so I'm not sure if I
did it right.

I also found a way to restore the video in OS X. After a suspend and
resume the video is OK, until the next reboot. So I tried "nvram -c" in
a terminal. I don't know if this does the same, but it didn't help.
