External monitor on IBM T22 with different resolution?

[Martin Skøtt <martin@z3n.dk>]

Hi 

I have just purchased a 17" external TFT display for my T22 (Savage IX
chipset), but I'm having some trouble getting it to work...

The built-in display runs at 1024x768 while the 17" display uses
1280x1024. How do I configure XFree in Debian unstable to use
different resolutions for different displays?

I tried adding 1280x1024 to the display section of XFConfig-4, but I
get the following in XFree86.0.log when starting X ctrl-alt-+:

(--) SAVAGE(0): Detected current MCLK value of 83.045 MHz
(--) SAVAGE(0): 1024x768 TFT LCD panel detected and active
(--) SAVAGE(0): - Limiting video mode to 1024x768

I guess I have to add a second Monitor section and somehow persuade X
to give me a possibility to change between the two, but how do
persuade it?
