Here are the stderr logs. x-0.log.old is the session that crashed from trying to "AutoAdd" the AMD GPU, and x-0.log is the session that loaded after the crash with the GPU loaded.
I paid close attention to differences in these logs between when I had AutoAdd turned off or on in xorg.conf, and there are only 2 different lines: the obvious "using xorg.conf" line (because I just deleted the xorg.conf file when I wasn't turning AutoAdd off), and the line that the .old file ends in if it crashes: "Xorg: privates.c:385: dixRegisterPrivateKey: Assertion `!global_keys[type].created' failed."
