I assume that means you have Radeon Mobility L7?

Why do you say that DRI must be switched off to use MergedFB?  I use
MergedFB together with DRI on my T42.

That I do not know, but I think it ought to be possible to achieve this
without MergedFB.

I have the same setup -- 1024x768 internal LCD + 1280x1024 external LCD.
I currently use MergedFB with 1024x768 on both screens (the external LCD
has a nice smooth built-in scaling algorithm (that sometimes malfunctions
until I power-cycle it, *sigh*)).

I've never tried to use just the external display at a higher resolution.
Maybe I'll find some time to experiment, although currently I'm
overloaded with work.
