I called ATI and there is a board design flaw that disables the board from
working in the 31.5 khz mode with some monitors (the ones that I had
qualified - and Ultra-14 and Mitsubishi 1429C).  The problem according to
ATI was that the board has internal filtering to pass FCC, and
likewise the monitors included filtering - thus providing too
much filtering and keeping the monitor from getting in sync with the ATI.  I
was issued an RA number, and ATI mentioned that they changed all boards in
stock and production runs to fix this problem.
