what sort of setting are you trying to achieve? dualhead? clone mode?=20
CRT only?  if you want to use mergedfb which it looks like you are
trying to do, you will need to specify the refresh rates for your
external lcd monitor using the:
        #Option     "CRT2HSync"          =09# [<str>]
        #Option     "CRT2VRefresh"       =09# [<str>]
options since those apply to the second crtc in that case.  if you are
using "regular" multi-head you would need to create multiple device,
monitor, and screen sections.
