are you trying for dualhead or just 1280x1024 on the crt only or a
clone mode with 1024x768 on the lfp and 1208x1024 on the crt?

you have two screen entries.  this is used for dualhead.  you only
need one if you want single head or clone.

if you are trying for dualhead you'll need to add:
Screen 0
here.  Also I think monitorlayout generally refers to the crtc order.
so the first entry would be crtc1 and the second would be crtc2.  that
doesn't reflect how you've specified your monitors or screen sections.
 reversing the order of the monitorlayout option may help, but I'm not
familair with the driver, so I don't know how it uses the option
internally (whether it switches the crtc/ouptut mappings or just
forces the outputs on)

you'll probably also need the monitorlayout option here too if you are
tryign to get dualhead.
