The polymorphic data is returned in a void* right? Why not just
change the result from HW_PHYSMEM et al to a size_t instead of
unsigned int? Systems that support >4G should already set size_t to a
64bit type and could return the correct value if `len' == 8.
Alternatively, we can try using mib[] = { CTL_VM, VM_METER } which I
believe returns values in pages. But I don't know if that works on
all the BSDs and Darwin.
