Upper half of the screen during hang

I'm the owner of a 15-inch late 2011 MacBook Pro. If I boot the system in the
default setup, it completely hangs shortly after starting the X server (at
least, AFAICT). If I boot with "nomodeset" appended to the kernel parameters,
then the system boots fine. This has happened for a long time now, so it's not
a recent regression or anything. I'm on Debian Unstable, with an untainted
kernel installed from experimental.

I will attach all relevant logs. All logs are from a boot with "nomodeset"
appended. I'll also attach photos of the logs that appear on the screen at the
time of the hang. These photos are from a slightly different kernel, but the
symptoms are the same.

I'm comfortable applying patches and building the kernel from source.
