I can power-off on shutdown (halt -p & acpiconf -s 5, if I understand
this correctly). mode 1 doesn't seem to do anything, but that might
just be because I can't notice the CPU stopped. 3 actually halts the
drives and the fans, but powering evrything back up gives me a nice
freeze. 4 just hangs.

Of course. I didn't think of that. :)
