Hi!
There are some regressions with xf86-video-ati as you can see, we are 
working on a way to resole this.
In the meantime, if you have any of the drm-next or drm-stable ports 
installed, can you check that they have actually loaded?
You need to add kld_list="/boot/modules/radeonkms.ko" to rc.conf to have 
the module load at boot, or manually, as root, do kldload 
/boot/modules/radeonkms.ko.
Please try to start X after this.

Can you please provide the output of kldstat -v if the module is loaded, 
or believed to be loaded.
Thank you!
Regards
