Ok I guess.  (But it really really looks like t_rm is treated as total
real memory in top src code.  It would have been nice if it worked or
if some other field mapped to total real memory since vmtotal contains
values in pages it should have been ok.  Anyway...)

Ok then let's go with that.  When you get agreement on the new
interface please proceed with a patch to physmem.c.
