We need to be moving towards a situation where people don't _need_ to
patch the hell out of their kernels to make Linux viable for embedded
devices. I'm not prepared just assume that 'they will always do so', and
I'm disappointed to hear Andrew say such a thing. 

It's simple economics, really.

Until they see value in upstream submission, it's always going
to be %100 invested in getting the current product out the door
or the current fire put out.

The odd I2C device hack of the day the do to one revision of their
product is likely never to be submitted upstream.  And these
embedded folks have hundreds of things on that level that they
sort out for each product, and often very little of it is reusable
in the next product.

They don't see the payback for upstreaming this stuff, and for
a lot of cases neither do I.
