My guess is that dynpm is unknown parameter and thus kernel refuse to load module (please provide dmesg with the parameter to verify this supposition). If that the case than there is nothing we can do, don't use this parameter.
In my configuration, according messages log : May 18 11:00:43 lx-xxxxx kernel: radeon: Unknown parameter `dynpm' but according my understanding this option should enable power management (just google radeon.dynpm).

This option doesn't apply to 2.6.33 (it might to 2.6.34) I am closing this as this isn't a bug. Just don't use parameter that are not valid.
