russell: they have more employees than sense :) they also don't have
any idea of what they *should* be doing, so this is an opportunity to
educate them.

they're not feeling any pain: they just employ more chinese
developers and substitute bodies for time and common-sense.

also, in this particular case, thanks to their script.fex system when
i said they only need to develop one kernel and one u-boot i really
wasn't kidding around: they really have got to the point which
everyone else dreams of with device-tree [admittedly by limiting the
product range that their clients can play with, but that product range
has huge returns, so they're still happy].

russell: the decision process they've made is actually an extremely
effective one.

i believe they have a technically more *successful* solution. whether
it's more appropriate in a wider context is another matter.

here we have a key to the crux of the problem: the linux kernel
maintainers have to cater for _everyone_. with no funding or
incentive from the major contributors to work with them. hmmm....

ok. so. we come back to the question again: what shall i propose to
them that they consider doing, and what benefit would it be to them to
do so?

i cannot go to them and say "you have to do this [insert proposal
here]" - it has to be more subtle than that.
