Is it possible to turn off power on a dual processor x86_64 board with
'halt -p' or similar? If yes then what is needed on a kernel level?
I know that this does not work with "distribution" kernels.
What about single processor boards (although I did not see yet
one of x86_64 kind :-)?

You need ACPI.

It works fine with SuSE kernels.
