still craps out.
this is what the code looks like now:

#include <sys/io.h>

int main() {
	iopl(3);
	outb(6, 0xcf9);
	return 0;
}
(hopefully done right).

as for the acpidump, I seem
to be hitting some error trying
to dissemble it, so I just grabbed my copy from:
https://bugzilla.kernel.org/show_bug.cgi?id=14483

what/where might I be looking for, for this reboot
port in the *.dsl?
