I've tried it both ways, and it doesn't seem to make any difference.

And since it won't tell me what it thinks the sync-timings of the flat-panel
are, I can enter those manually into xorg.conf in the "Monitor" section.

I also can't tell if the built-in screen is LFP, and if it's on PipeA or 
PipeB,
etc...

You'd think the BIOS would know the modeline for the native resolution
of the panel!

I hate VBE.

Grrr.

Usually the Dell hardware is fairly solid.  Are we positive that there's no
VBE mode for 1400x1050?  I made some minor changes to the config...
now I'm not getting that warning any longer, but the local flat-panel is
coming up 1280x1024...  As if the settings for the two monitors were
backwards...
