I added the 1600x1200 to the front of the Modes in the screen section, though 
I did have it there previously as the 2nd element. (see mode line from above)  
I'm still finding that mergeFB disables itself because it cannot figure out 
the modes and/or metamodes. 

I'm not sure if the order of the metamodes matters (1024x768-1600x1200 as 
opposed to 1600x1200-1024x768), so I added the later without any success. I 
also tried setting my monitorlayout option to lvds, crt  but as that didn't 
help I removed it once again.

How have I manged to screw up the modes so mergeFB doesn't understand them?  
Or is there another part of the configuration I'm missing?

I appreciate the hand-holding.  I sure would love to get this to work!

Thanks,
