Well, pstat -s reports it, and it gets it from struct anoninfo anoninfo.
This struct seems to be defined in /usr/include/vm/anon.h.  It's not 
per-disk, though; if you need per-disk, each disk vp set up for swap
is noted in struct swapinfo *swapinfo, which is defined in
/usr/include/vm/swap.h.  You'll probably have to chase the free list 
yourself, using (again) /usr/include/vm/anon.h.
