Thanks, Steffen. Your idea was the solution!

I decided to get to work early tonight....

First I tried a depth of four bits, but it was rejected by
dpkg-reconfigure as not available for my video card.

So I tried eight bits and it is now working at 800x600. The 16bpp needs
960 kB, so it should also work.

My calculations also indicate that 1024x768 at 8bpp will work (786,432
Bytes required). Do you agree (is my math correct)?

Also, now with the real monitor sync range, is the pixel clock still a
concern?

Here is the newly-generated xorg.conf with only eight bits selected for
the depth.
