@HwRhymes: The bios certainly could be to blame, but resume hangs are extremely hardware specific, so unless the commentor on the freedesktop bug you linked to had an identical machine it's hard to say whether or not it's the same problem.
@Marc: Something is getting stored in the resume trace but the kernel could't find the matching device. One possibility is that the hang was in a kernel module that wasn't loaded when the pm_trace output was generated during boot. Could you try the pm_trace again, but this time after fully booted run 'cat /sys/power/pm_trace_dev_match' and paste the output here?
