I can confirm that it did fix the problem running on a Linux host, but the OS X bug cited by myself and the OP still remains elusive. It's rather puzzling as I pulled from HEAD and built using the same options on both. I've gotten a bit better with the qemu options now, so I will paste the console output here instead of doing yet another screenshot :) As you can see, it's still getting a fatal exception in the interrupt code. Do you know of a kernel version that would be better behaved than the 3.6.11+ from the "raspberrypi/linux" repo on github?
