Arjan, thank you for reading my prolific manifesto.  I am not arguing 
for the interface being desirable, and I don't think I'm being self 
contradictory.  There was some confusion over technical details of the 
VMI gateway page that I wanted to make explicit.  Hopefully I have fully 
explained those.  I'm not trying to get a license exemption, I'm trying 
to come up with a model that current and future hardware vendors can 
follow when faced with the same set of circumstances.

It was not 100% clear based on conversations at OLS that open-sourcing 
the VMI layer met the letter and intent of the kernel license model.  
There were some arguments that not having the source integrated into the 
kernel violated the spirit of the GPL by not allowing one to distribute 
a fully working kernel.  I wanted to show that is not true, and the 
situation is actually quite unique.  Perhaps we can use this to 
encourage open sourced firmware layers, instead of trying to ban drivers 
which rely on firmware from the kernel.
