You could take this information and put it into a ModeLine in your
configuration file.
Section "Monitor"
#Other stuff here
ModeLine "1024x768" 78.654 1024 1056 1184 1312 768 772 776 792 #76Hz
EndSection
However, this is a workaround and the X server should have figured
this out for you automatically.

Evidently, the X server thinks these modes are too fast for your
monitor. Check /etc/fb.modes and man fb.modes for possible
information.
