This is just a thought of mine:
/proc/slabinfo?

cat /proc/vmstat | grep nr_mapped
nr_mapped 77105

But yes, this doesn't give you a detailed account.

Again, this is just a thought of mine: Couldn't you get this information 
from /proc/<pid>/maps or from the nicer and easier to parse procps 
application: pmap <pid>?
