The APM code is i386 specific, and the Sun power-management code 
(should it exist) would be Sparc specific, and if there's an Alpha box 
with power control, code for that will be Alpha-specific.

So what?  Power down means power down.  Halt means halt.  The two are 
different things, even if one or the other doesn't have a significant 
meaning in a given special case.  There are good reasons to halt an 
i386 system rather than power cycle it, even if APM is active.

How hard is it to change _one_commandline_option_ when you call
shutdown(8)?   Come on...
