Dmesg output for kernel 3.17.6

Since kernel 3.18 I'm no longer able to run X on my machine. While
3.17.6 is fine, 3.18 leaves me with a black screen when starting
X. Booting into runlevel 1/3 is fine.

I did a "git bisect", and the offending commit is this one:

[root@kiera linux-git]# git bisect bad
83f45fc360c8e16a330474860ebda872d1384c8c is the first bad commit
commit 83f45fc360c8e16a330474860ebda872d1384c8c

    drm: Don't grab an fb reference for the idr

[....]

I double-checked, and 3.18 is fine with this commit reverted.
My machine is an Asus U45JC laptop, and the CPU is an Intel i450M
(Ironlake).Please contact me if I can help in any way.
