I've done exactly that, stuffing the postscript for the letterhead
down before the Adobe prolog, and it works fine.  Maybe there's some bug
in your postscript.  This is what I do (memoline1 and memoline2 are
def'd to be the name and address of the department and pushed down
by the shell script in advance of this file):


gsave
/rutgers {
/scfactor exch def
/logow 656 def
/logoh 207 def
logow scfactor div logoh scfactor div scale
656 207 true [ 656 0 0 -207 328 0 ] { <
