I narrowed the problem down to this specific change:

2009-12-04  Stefan Monnier  <monnier <at> iro.umontreal.ca>

   Minor cleanup.
   * term.el (term-send-raw, term-send-raw-meta): Use read-key-sequence's
   key decoding rather than do it manually via last-input-event +
   ascii-character.

I'm not sure if the change to term-send-raw breaks anything, but the the
change to term-send-raw-meta definitely prevents the process from
getting M-d correctly.  I've reverted it in the repository for now
(change attached), but you might want to double-check the entire change.
