Comment (by wmb at firmworks.com):

 I verified with an OFW test the that DCON dotclock divisor can be switched
 back and forth between 50 Hz (divisor 0) and 25 Hz (divisor 1) when in
 screen-frozen mode, without visible glitches.  Other divisor values cause
 display glitches or flicker, but shouldn't be used anyway because of panel
 life concerns.
