Comment (by kallisti5):

 building the accelerant and driver and dropping into the folder may not be
 a good test... a lot has changed in the image since A3. Could you test the
 latest nightly from an iso or dd'ed onto a usb drive?

 radeon_hd: connector_read_mode_lvds: 108000 1400 1444 1556 1684 1050 1051
 1054 1066

 That shows AtomBIOS is actually reporting a lvds mode of 1400x1050 for
 this card. Is 1400x1050 the correct native resolution? We pass that value
 back to Haiku as the preferred mode if a preferred mode is found.
