Radeon blanking broken

The radeonfb blanking rework has broken it on the iBook G3 wit Radeon M6.
When the X server enables DPMS the backlight stays on and the display gets
in a strange state, gradually fading off.  When I revert the changes to
radeon_screen_blank, radeonfb_blank and radeon_set_backlight_enable it
works again.

This is a real pain actually... I can't seem to find a sequence that
will do proper blanking of the LCD on all models... 

It seems each LCD model need a slightly different set of timings etc...
for the blanking procedure.
