Why do you think you have to provide this additional information? Let the 
frame buffer driver compute them. Therefor, as William mentioned, specify 
the cmdline variable in file /boot/uEnv.txt like

Note the "M" after the resolution here. It requires individual calculation 
of the timings (in contrast to reading them from a pre-defined table, see 
framebuffer documentation for details). That way you can skip EDID and 
specify any resolution in a convenient way. I guess RPi provides a similar 
feature, and you need not manually handle them using the config.txt file.
