The new kernel also has the same address range partitioning as Linux 
and Windows - we'll see how far we'll come with this (and if we have to 
change it later on).
Since Wine and LxRun both need it I think we should try to keep this 
layout, but if we need to change for keeping compatibility with BeOS, 
we will (before reading this thread I wanted to change it just to keep 
the number of possible problems at a low number :-)).

Adios...
