Testing current 3D on r600

[Marcin Baczyński]

Hi
Could you tell me what I need to test current 3D on my RV630?
I have drm-next kernel, current git master mesa and xf86-video-ati
and X.Org X Server 1.6.3.901 (1.6.4 RC 1).
The problem is that when starting X I only get this error:
X: symbol lookup error:
/usr/lib64/xorg/modules/drivers//radeon_drv.so: undefined symbol:
drmCheckModesettingSupported
What am I doing wrong?

Thank,
Marcin
