With one minor nit (sparc64 needs #ifndef SUN4U around __HAVE_MM_MD_READWRITE)
this compiled and I tested a few archs, by running a very limited test:

  vmstat -N /nebsd

sparc, sparc64 and mac68k seem to work.

Not working:

alpha:          vmstat: kptr fffffc00005bbe00: boottime: kvm_read: Bad address
prep:           vmstat: kptr 2bc9b0: boottime: kvm_read: Bad address
sgimips:        vmstat: kptr 8031888c: boottime: kvm_read: Bad address

If you have any other tests, let me know and I'll run them.
