Thanks for the tip, this looks promising.
I gave it a quick try, but there are a lot of rejects when applied 
against
3.13-rc1, and although i think i managed to fix some, there are also 
some
that I feel are (currently) beyond my skill to fix.
Probably i need to study this some more, or try an earlier kernel.
Either way it will keep me busy for a while.

Mark.
