I don't have an official answer for you, but when I wanted to do
something with these entry points a couple of years back I discovered
that they aren't very thoroughly implemented across the various
architectures.  I started cleaning this up and can probably dig up
some of this for you if you need it.

See:

Then again, this may be in better shape  today, already... I didn't check.
