I'm seeing the exact same message on my thinkpad t430s.
When I try your patch, modesetting no longer works. When it tries
to change to the framebuffer I get a black screen and lockup.
If I boot with nomodeset it locks up when it gets to X.
It all scrolls by too fast to read, but it looks like there's still
a backtrace present.
