As expected, the patch doesn't change anything.

OK, I tried again. This time linprocfs and even linsysfs where mounted.
No change at all, the error message stays exactly the same as shown
above. 

I realy would like to see this issue fixed, but I don't know anything
about the internals of DRM. So the only short time help I can offer is
providing informations. If you need more, just tell me.

Ciao,
Yamagi
