Hi Rico,

I have to apologize, I asked you for the wrong info. Upstream tells me that radeontool output is only valid for pre-R5xx series chips. For r500 and newer, including the R500-based X1400, they actually need the output from avivotool. This probably explains why you saw no difference between the two radeontool outputs...

avivotool is in the radeontool package, so you already have it installed. Would you mind please re-running your two cases again, and instead collect the output from avivotool? Run it like this:

  avivotool regs all > avivotool_good.txt

Thanks ahead of time, and sorry for the incorrect directions I gave.
