Comment 6 for bug 556232

I also tried to see what the registers shows with radeontool. I'm attaching the two outputs.
A diff produces this:
root@aje-laptop:/root# diff regs.10 regs.19
8c8
< RADEON_AUX_SC_CNTL 97035a08

> RADEON_AUX_SC_CNTL 97035a2c

(top is the -10 kernel, botton is the -19 kernel)
I tried setting the registers to the top values on the -19 kernel, but it silently ignores my attempts to set them.
