Follow the source.
For 10.6.3 @ http://www.opensource.apple.com/source/xnu/xnu-1504.3.12/
madvise in bsd/kern/kern_mman.c
leads to
mach_vm_behavior_set in osfmk/vm/vm_user.c
leads to
vm_map_behavior_set in osfmk/vm/vm_map.c
which appears to implement all the various map operations (in particular DONTNEED and FREE)
