There is no radeon.debug parameter:
[ 34.991462] radeon: unknown parameter 'debug' ignored
Seems like you just got lucky this time. Does it work reliably if you disable
radeon and boot into a non-X runlevel, then manually load radeon? E.g., boot
with:
radeon.modeset=0 1
on the kernel command line in grub to boot into single user mode. then at the
command prompt:
modprobe -r radeon
modprobe radeon modeset=1 dpm=1

You can ignore those.</pre>
