that would work if everything is swappable. It is hard to fight those holes
when drivers that need wired contigous memory come and go through lkm
loads/unloads. 

Most driver allocations would puke if their memory got moved unless we go
to a double pointer arrangement, but (aaaaaaaaaahhhhhgg) I would not have
to be the one to have to debug VM problems).
