I like the idea.
1. I think an idea like that needs first some advertisement to make people aware of the action.
2. Financial is basically a kind of bottleneck. More money means more manpower and thus more progress. Of course it doesn't help against missing specs besides the horrible work of reverse engineering. Still manpower. So yes, finances can be a sort of a bottleneck for driver development.
3. And I personally would prefer if there was maybe also a kind of choice what to do. E.g. I have an interest in getting GPUs soldered with ARMs afloat, AMD UVD working (and some more energy related stuff, everything else is fairly ok and progressing by official development) and maybe some love for these pesky VIA chips.
Or hire somebody to get BluRay-CSS or whatever it's called decoding airborne. Might not be totally legal in all countries but what can you do if you want to watch the movies you bought on Linux or BSD?
Or make past chips that are still not well supported working. GPUs, WLAN, some USB devices, omg printers(!) and whatever else is still having problems.
Stop TCPA, stupid software patents and corrupt politicians!
