I had that working perfectly (T42, Radeon 7500, 1024x768 laptop panel,
1280x1024 external LCD monitor), in several ways, with the pre-randr-1.2
radeon driver.  You could take a look at my xorg.conf:
<http://mg.pov.lt/xorg.conf>.  It has lots of comments (may outdated)
and (too many) alternative configurations (expressed server layouts).

IIRC I had to boot (or maybe just restart X) once with the external
monitor (1280x1024) plugged in.  After that I could
suspend/resume/plug/unplug the external monitor at will, switching
between dual-head and clone modes with xrandr.

Hacking graphics in X is like finding sqrt(pi) with roman numerals.
