Further DRM report on Intel chipset

[Vincent <10.50%free.fr@localhost>]

Hi folks,

Well, the DRM with Intel is making progress, but I am still unable to 
get it work, even with the latest 2.2.1 driver and the latest drm code. 
But it is much better than before: I get a neat error code.

Now DRM_DEBUG shows this:

So there seems to be a bad ioctl call. Any clue? I am going to dig 
farther in the code.
