I do not know, but my xorg.conf used to have the HorizSync and the
VertRefresh lines forever. But you are correct that eg the intel(4)
driver seemed to ignore it, while the vesa driver takes note of it

Well, looking at the config and the log you posted, there appear to be
several interesting things.
1) It seems you are trying to use a multi-monitor config (with Screen1
commented out.) You say one of these is the LCD of the laptop. What is
the other? Are you testing with the LCD only? (It seems so from the log,
but doesn't hurt to be sure)
2) The video ram found by vesa(4) is very low (mine finds 8000kB):
(II) VESA(0): Total Memory: 13 64KB banks (832kB)
It would be useful to try to investigate why. (Do you have agp activated
in your kernel? I do, although of course vesa provides no acceleration
in that area.)
3) This is interesting:
(II) VESA(0): Attempting to use 85Hz refresh for mode "640x480" (111)
Is this Hz value correct for the display you are testing with? My LCD
says 60 Hz.
I am sorry that I cannot give you more direct advice, but maybe there is
somethine in there which may give you an idea...
