I dunno.  I'll leave that one to Steve or Frank.

I added code to mapserv.c in the "obvious place" where the CGI form variables are parsed; this looks for an IMAGETYPE variable and sets msObj->Map->imagetype to that string value.  However, it appears that in the earlier processing of the MAP file, the outputformats are enumerated and the default selected.  My setting of msObj->Map->imagetype has no effect because it seems the decisions' already been made.

You'll have to call msSelectOutputFormat() for the output format change
to take effect.
