A small step in the right direction is a good thing. I'll run the patches 
by you first.

The existing license isn't that BSD-friendly either, which is why it lives 
in contrib/. I think the 5.1.X GPLv2 is about the same friendliness as 
Darren's IPF 4.1.X license. As long as it's not in GENERIC should be fine. 
A person can always load it anyway.

Agreed. I looked at it a few months ago and determined that src is where it 
should be. (I put it aside, getting ACER WMI/ACPI working on my new Acer 
laptop was my priority at the time.)
