that's pretty much the case... param points to something called a
"logout frame", which has CPU, core logic, and system variant specific
data in it.

...however, you'll notice that NetBSD can interpret the logout frame on
some systems... i.e. some of us have the documentation necessary to
write this code... it's just a matter of doing it, really.
