From what this site http://wiki.x.org/wiki/RadeonFeature says, KMS
seems to not yet (fully) support your card.

You should add radeon.modeset=0 and probably a vga or vesafb options to
your kernel parameters in /boot/grub/menu.lst.

As far as I read KMS for radeonhd cards is planned for kernel 2.6.32.
