real shutdown SMP and Alpha?

my question is not exactly FAI related, but probably the expertise is here:
I have to shut down a really large number of (a) SMP-686 and (b) Alpha
boxes on request. This should be done by software (and for (a) I did this
by compiling my own kernels, with apm-real-mode-power-off set to y) to 
still be able to etherwake the machines if necessary. 
I want to avoid making my own kernel (mostly for security reasons).
Is there a safe way to achieve power-off (not only "Power down." written
to non-connected consoles) for instance by kernel boot parameters?
(b) How to switch off an Alpha from software?

Cheers, and thanks
