Did dpm ever work on your board?  Just to clarify, does 3.13-rc5 fail to boot
even with radeon.dpm=0?  Please attach a copy of your dmesg output, Xorg log,
and vbios.  To get a copy of your vbios:
(as root)
(use lspci to get the bus id)
cd /sys/bus/pci/devices/<pci bus id>
echo 1 > rom
cat rom > /tmp/vbios.rom
echo 0 > rom

Unrelated.  That bug is about rv6xx asics.  Your chip is a BTC part.
