Actually, you can have two fairly close modes, and all that really matters
is that they are labelled differently (most modenames are res' names but this
isn't required at all).  So, you can have your original modeline for 800x600,
insert the vidtuned setting that makes your monitor even happier and call the
second "800x600a" -- then switch between them.   Two problems solved at once;
improving the looks of the monitor as well as the LCD, and getting the modes
to otherwise pretty much stay the same.

I wonder if asapm or any of the other X-based apm tools could help you with 
this trouble, by keying an extra action into the resume event.
