I am pretty sure: If one of the kernel developers had the specifications from nvidia, this patch would have been there in no time.
Now they can put this far far down on the todo list, some nonpriority matter, of some nvidia's coders and let the users wait and beg for these drivers.
And now the faithful nvidia board posters scream out "thank you for your mercy and generosity! thank you thank you!" ... this reminds me of microsoft's police ...
Thankfully people like chief notice that this is not the way to go.
