OK, I see this point. It is hard to have a default that makes everyone happy.
The other scenario is where one uses a laptop for a presentation.
This however requires that the dpi of both displays match.
This would not be the case for my laptop (1680x1050) vs. my much bigger lcd
with 1920x1200. Here of course one could use scaling to make this match.
There this person might want to see exactly the same on the laptop display as
is shown on the screen.

OK, thanks. The 'FAILED' log file message I've included in one earlier comment
troubles me. The reason is not specified so it's even harder for me to guess
where it originates from. Today I committed code to make the message  even more
verbose. Can you get the latest git sources, start the xserver with verbose
level 7 again and use xrandr to try to switch the panel to native mode?
This worked well here and i don't understand why it doesn't work for you.
I need to find out what validation test fails in your case.
I was using a similar setup as yours only that my laptop is 1680x1050 instead
of 1400x1050.

That's exactly the problem: it's a policy decision done by randr. The general
believe there is that people will have some desktop thingy which will store the
last configuration on log out and restore it the next time the user logs in. So
the goal is to do away with a config file as much as possible.
In your case I unfortunately have no clue how to set this up. You'd have to
instruct randr to set each display to its native mode.
