[ 13.127] (II) RADEON(0): Output DisplayPort-0 connected [ 13.127] (II) RADEON(0): Output DisplayPort-1 connected [ 13.127] (II) RADEON(0): Using fuzzy aspect match for initial modes [ 13.127] (II) RADEON(0): Output DisplayPort-0 using initial mode 1152x864 [ 13.127] (II) RADEON(0): Output DisplayPort-1 using initial mode 1152x864 The xserver (not the driver) is picking 1152x864 since it's the largest common mode supported by both monitors. You'll have to use xrandr to choose a different mode (or specify different default modes in your xorg.conf). Alternatively, you can start up X with one monitor attached and then enable the second one manually with xrandr.
