No effect. I tried it from both an xterm in the corrupt X session and from the
console before running X. 

> does the following help (when the screen is corrupt):
> radeontool regset RS480_UNK_e38 0x8000021b
> radeontool regset RS480_UNK_e3c 0x000004d2
> 
> you may want to do a dpms cycle after you change them (xset dpms force off).
