TBH I have backed up deprecated port graphics/drm-legacy-kmod and use it 
on 13-ALPHA. The port graphics/drm-current-kmod was unusable (console 
resolution, flaky gdm start etc.), tough no panics were observed.
One should be still able to build graphics/drm-legacy-kmod on 14-CURRENT 
for some time till the issue gets resolved.
