Try this:

Option "MonitorLayout" "NONE,CRT+LFP"
Option "DisplayInfo" "true"

The second line will help you to analyze the problem if the
MonitorLayout option doesn't work.

These chips have 2 pipes, mine uses pipe B for the LFP (Local Flat
Panel), so I tell the driver to use the pipe B for both the LFP and the
CRT.  

The DisplayInfo option will show your pipes and the attached devices in
the log file
