I just double-checked it again on a couple of my systems and it seems to
deny loading the module correctly.

What kind of hardware is this?  Could you send me 'dmidecode' output?

I'm wondering if your hardware matched the "Intel" string somehow and
the dmi code didn't bother to check anything else.  I'll also go try and
run on a few more pieces of hardware and see if I can get it to trigger.
