yep. We know and have discussed this with Paolo already.
Kernel stuff is in progress at the moment. The patch
is presented to interested people to allow to compile and
run.

Actual merge will be performed with proper sync
when kernel will be in rc3 or 4 stage and the patch will be
dropped.

The same applies for patch 5.
