A problem with similarities, but slightly different affects me (and 3 others). I' ve posted a full report in Bug #573290.
I have an ATI mobility Radeon X1400 card. My second monitors (HP1530 and HP L1820) give the message " signal out of range" and just a black screen.
I tried the following solution, but it didn't help: adding "options radeon modeset=0" to /etc/modprobe.d/radeon-kms.conf
I hope this extra information can help someone solve the problem.
