this line should probably be:
         Option "MonitorLayout" "LFP,CRT"
or:
         Option "MonitorLayout" "CRT,LFP"

you might also want to try Alan's latest i810 driver here:

the i810_drv.o (or i810_drv.so) in /usr/X11R6/lib/modules/drivers are
the only thing you need to worry about for 2d and multi-head.  the
i810 and i915 kernel drm modules are only needed for 3d accel.
