They should work without wakelock since wakelock are optional .. I mean
there's nothing in suspend blockers I've seen that indicates it's
required for some drivers to work. So it's just a matter of patching out
the wakelocks, with no need to re-test anything.

You get the driver mainlined, then maintain a small patch to add
wakelocks. Not hard at all , with lots of incentive to do so since you
don't have to maintain such a large block of code out of tree.

I don't see why your saying that. These driver should work with out all
of this, which means they can get mainlined right now.
