That's a completely different thing.

Example for what I'm talking about:

Customer says:
We know $driver in the kernel for their device is buggy, but they are 
the only ones manufacturing this kind of device we need.

Customer uses the device as part of some machines he sells.

Neither the manufactorer nor the customer do want to _ever_ become 
publically known that there are bugs in the device.

And that's not a made-up example, I know names for manufactorer and 
customer for such cases.

We do not need more sophisticated statistics, we need to find ways to 
get the bugs fixed.
