Impressive work, thanks!

That last patch is a bit controversial. I am not sure this is the right 
direction to add a new profile for every combination of quirks. At the 
very least, we should have a mechanism to include basic parts (and I 
think UCM already has a concept of include). Or better one UCM file that 
combines all possible combinations and disables some parts based on 
quirk information fetched during initialization.
