This code is used only if you have a driver around that supports EDID. 
The boot loader doesn't use it, so this at least cannot be the issue 
here. Specifically the VESA driver does not use any EDID information to 
build its mode list (only for selecting the right mode, as the timings 
cannot be set anyway).

IIRC this is since your Intel Extreme based system doesn't like the 
1920x1200 screen anymore (as it tries with that resolution), and that 
sounds more like bug http://dev.haiku-os.org/ticket/2791.
