hrm nothing is jumping out at me yet.

can you post a dmesg from when you boot the system and enable loading 
the radeonkms.ko via rc.conf like so:

kld_list="/boot/modules/radeonkms.ko"

it should have a bunch of loglines prefixed with [drm] - that should 
show us if the driver is attaching correctly.

looking at the Xorg.0.log you sent I don't see anything obviously wrong 
aside from this:

[  1675.580] (II) GLX: Initialized DRI2 GL provider for screen 0
[  1675.586] (II) RADEON(0): Setting screen physical size to 677 x 381
[  1675.648] failed to add FB for modeset
[  1675.648] (WW) RADEON(0): Failed to set mode on CRTC 0
[  1675.657] (EE) RADEON(0): Failed to enable any CRTC


hopefully there will more useful info in the dmesg buffer when you load 
the radeonkms driver vi rc.conf.  one final thing you can also try is 
uninstalling the drm-kmod package and installing the "drm-legacy-kmod" 
package if you haven't tested that already.
