Thanks for the suggestions.

By "CRT number", are you referring to the CrtcNumber option?  I have
tried both 0 and 1, and noticed in /var/log/XFree86.0.log the
following message:

  Detected CRTC controller 1 being used

So I've been leaning toward a value of 1.  Does that seem off?

I noticed that the page referred to by the URL you posted has the
following text:

  This script is based on my experience on high-end monitors (17"-24"
  multisync with more than 135Mhz of bandwidth), trying to squeeze the
  most refresh rate at the highest resolution, and will not work for
  lower specs monitors (15" and lower).

Do you think it might still work for a 15 inch flat panel iMac?

Also, I was able to track down some information about the LCD screen
in the tech specs -- something about it being able to do 1024x768 at
75Hz (the vertical frequency?).  The script asks for at least:

  Max Bandwidth
  Max Vertical Frequency
  Max Horizontal Frequency

Do you have any ideas where I might determine values for bandwidth and
horizontal frequency?

Thanks for any help.
