In the heirloom version of mm the display is processed in
environment 1, which still has the original line length.
To fix your problem, you could replace

  .ll 6.5i


  .ll 6.5i
  .ev 1
  .ll 6.5i

However, mm already provides a mechanism to do this
automatically, by setting the register "W" to the
desired width *before* loading the macro package.

I.e., you can either

  tbl |troff -rW6.5i -mm |dpost >

or, in your manuscript, do

  .nr W 6.5i
  .so /path/to/mmt

and then run troff simply as

  tbl |troff |dpost >

(without -mm).
