Since you are the author of the "pmap" utility by some coincidence:-)

It would be great if "pmap" could show which pages of a map entry
are backed by anons. Currently it only shows (with -d) whether an
amap got allocated at all.
(would have saved me a lot of digging with gdb when I was PICifying
some assembler code recently)
