wonder why planb works at all....

Probably because no one stumbles across the memory it is trashing?
Currently, bad_thing_will_happen = vmalloc + virt_to_bus + dma.
It could be with the right memory size, modulo addressing, memory
controller configuration, timing of the vmalloc, it just may
accidently work.  If this is the case, I would be out buying
lottery tickets........

Ok, my apologies, planb doesn't use vmalloc at all these days.  So, there
is no problem of that kind.  (In the beginning, it had vmalloc with a lot
of problems as I recall now.)
