--- Comment #15 from Niels Ole Salscheider <niels_...@salscheider-online.de> ---
The output seems to be missing?

I wonder if the problem has something to do with rendernodes.
The platform code opens /dev/dri/card0 when no display is supplied but the
pipe-loader code seems to open a render node (/dev/dri/renderD*).
The RADEON_INFO ioctl that fails has DRM_AUTH|DRM_RENDER_ALLOW as access
restrictions. This means that the ioctl can be called from render nodes, but I
am not completely sure what DRM_AUTH implies and if that can cause it to fail
when using /dev/dri/card0.
