Hello,

I have a Radeon 4850, and I'm using the drm-next branch of airlied's kernel
sources.  I have mesa, xf86-video-ati, and libdrm from git.

I have two monitors.  The screen on the right is 1680x1050 (DVI-1), and the one
on the left is 1280x1024 (DVI-0).  When I use KMS it only uses one screen,
which by default is the smaller, left screen.  If I disable KMS everything
works fine.  Xrandr sees both screens, and shows the correct modes.  If I do:
xrandr --output DVI-1 --mode 1680x1050 it changes the mode on DVI-0 to
1680x1050 instead of DVI-1 even though the mode is too large to fit that
screen.

I am attaching my dmesg, Xorg.0.log, and my xorg.conf
