[FreeBSD/X/Radeon] could not suspend/resume on ThinkPadX31 with latest X

I updated X server system(xorg-server-1.7.7_11,1) on ThinkPad X31/FreeBSD-11-current(around 23/Dec/2013).

Latest X server requre drm2 kernel module, however drm2 kernel module(only radeon?) does not support suspend/resume(see below commit log).
