weston-launch -u as root

If I try to start a weston instance by using weston-launch, while gdm on X is
running I get the following kernel message :

[di mrt  3 09:39:01 2015] [drm:radeon_cp_getparam_kms] *ERROR* invalid ioctl
with kms radeon_cp_getparam_kms
[di mrt  3 09:39:01 2015] [drm:radeon_engine_reset_kms] *ERROR* invalid ioctl
with kms radeon_engine_reset_kms

weston-launch refuses to run, attached a log of its debug output.

kernel - 3.19.0
libdrm - 2.4.59

RS780

weston/wayland 1.7</pre>
