Thanks. After having a look at it seems concerning viafb to be mostly 
Haralds patches with 1 or 2 extra ones.

Feel free to add the things you like. The main objective is probably to 
get things working and stable. I do not have an idea how good that will 
work out as I don't know how much code that requires. If you think 
that's the way to go, then we'll try it and see whether it leads to 
something usable and maintainable.

Jep, that's fine with me. I'll try to rebase&integrate the patches I 
consider interesting from Harald's tree in -mm. I guess that's a good 
thing to do as that's the latest used common base.
Any objections?
