See if you can isolate what PLL radeondump is reading that fixes things. It starts out by looping through the PLL index starting from 0x00 (line 139 of radeon_dump.c). Maybe step through it and see which PLL reg fixes it.
Can you test the randr-1.2 branch of the radeon driver and see if it works better for you?
Several options to try:
