I don't understand the problem.  Using SETDP is an optimization and
most code that uses it, will work without it.  (Removing the SETDP
shouldn't cause any major problems, the final program will just be
slightly larger and slower.)

The work around is to use the <> convention on the instructions the
assembler would have normally saved one byte on.  (Of course, simply
removing SETDP is also a work around.)  

Note: I haven't programmed the 6809 in about 3 years, and may be
getting something confused.
