I confirm this issue and can be reproduced easily using xset(1) when a
KDE session is opened:
DISPLAY=:0 xset dpms force off
DISPLAY=:0 xset dpms force on
# Screen frozen
The bug doesn't show when using a lighter window manager (eg.
x11-wm/awesome). I'm currently debugging this.
If you want to try my development branch
(https://github.com/dumbbell/freebsd/tree/kms-drm-update-38), which
contains an updated DRM code, DPMS works perfectly. But so far, I
couldn't nail down the culprit in HEAD.

Yesn that's expected, as we currently don't support multiple video cards
sharing the same set of output connectors (and 10.0-RELEASE won't
support this either).
