I do. Unfortunately I've been swamped, and still am, with other stuff, 
and have had zero time to work on it :-(.

My current plan is to finish the FSM rewrite for/during the September 
commit fest, and submit a patch for dead-space-map driven VACUUM for the 
November commit fest.

My original plan was to enable index-only-scans using the DSM as well 
for 8.4, but it's pretty clear at this point that I don't have the time 
to finish that :-(.
