external monitors don't work with ATI Mobility chipsets in XFree86 4.0.2 unless you add the option "crt_screen" to the ATI Device section in /etc/X11/XF86Config-4. Talking to the driver author, this is was to avoid panel damage in the current driver; XFree86 4.0.0 did things in an unsafe way, so while it worked, it was dangerous for the health of some panels.
