dmesg output from startup
I've got a MacBookAir2,1 with an NVAC/9400M. LVDS works fine with the patch
from bug #29171, but whenever I plug my Dell 2407FPW in via a mini-DP -> DVI
adaptor, my log quickly fills up with:

LVDS flickers a bit while this happens, and eventually the machine deadlocks.
Let me know if you'd like any more logs, etc; I've attached the relevant parts
of dmesg from startup, but I'm not particularly sure it's useful.
