Hi Krzysztof,

Thanks for your reply. I think I misremembered it from when you
originally said this in the other thread and thought you meant
you were unlikely to ever do it, not just for doing it soon.

No need to rush things then by removing it prematurely then, but it
might help if you could point to a git tree with your last working patches
in case someone else has a Laguna and wants to update it to a more
recent kernel before you do.
