DMESG Log from kernel 3.4.0 w/ hdmi audio disabled

The radeon hdmi output using radeon.audio=1 boot flag on kernel 3.4.0 causes
the system to become unusable because the display winds up having the frequency
changed to an invalid range. This shouldn't have happened since the only change
was the kernel, and all the user space was left alone.

System Information:
Linux Mint 13 ( amd64 see: http://www.linuxmint.com/rel_maya_whatsnew.php )
4GB DDR3 memory
Radeon HD 5770 
Athlon II x4 630
Gigabyte GA-MA790XT-UD4P
Emerson 40" tv ( for hdmi output )

NOTE: When I tested the 3.4.0 kernel i did not update the user space, because I
expect that the user space should not need any changes to have hdmi audio
working because the closed source driver already has working hdmi output using
alsa. So besides just using the generic kernel, the only flag i set when trying
to get hdmi audio out was the radeon.audio=1 boot parameter.
