The mechanism does not work anyways in the general case: in the standard
distribution an SMP kernel has the same module name as a UP kernel. A lot
of datastructures are different on SMP because the spinlocks change offsets,
even on 2.2 (on 2.4 nearly everything contains a spinlock or two). If 
you haven't hit that problem with AFS yet you were just lucky.
