I was trying to eliminate things having no impact in any event. Those all had

Section "Monitor"
  Identifier   "Monitor[0]"
  HorizSync    30-107

If as you wrote upthread the only problem was inadequate built-in HorizSync, 
then AFAICT the above should have
been all that's required. But, using it (with VertRefresh added also) starts at 
800x600, which is the maximum
selection in krandrtray.

I was able to trim the 11.2 copy a bit further while retaining desired startup 
characteristics:
