What I've got is an ATI radeon 9600 m10. I've tried the fglrx ati packages to no avail. I am sure the card is capable of dual heads but I am having problems writing a proper xorg.conf and also the installation shell script with the ati package just doesn't seem to be modprobing the ati driver into kernel space at boot-time. I had this problem about four years ago with a laptop with an nvidia card in it... I waited about six months and the nvidia support got better... I don't want to wait for ati's linux support... they are after all doing the xbox360 so my guess is they will be a little behind the curve on things linux in the near future.
