Public bug reported: I installed fglrx and fglrx-amdcccle, ran sudo amdconfig --initial and rebooted, and the machine hung. Rebooting into failsafeX mode behaved the same. Luckily there had been a kernel update since the beta, so I could boot into failsafeX mode using the grub entry for the previous kernel and purge fglrx from there. (failsafeX didn't really work either, but it gave me a rootshell.)
I'll attach whatever I found in the syslog for a hanging boot attempt.
