That is not recent. The patches I've committed to xrandr were in late November. The radeon driver (to the best of my knowledge) does not reflect the full capabilities of the hardware in randr, therefore it probably does not fall into these pits. Please retry with a recent version of xrandr. This is actually a FAQ. If it doesn't work with current git, we would have to dig deeper into that.
and, when I act on one output with xrandr, both change together. For instance, if I type
xrandr --output VGA_1 --right-of DVI-I_1/digital
both output go to (1024,0). I always get same resolution and same
It fails to unclone the CRTC. The radeon driver probably doesn't use
cloning at all, and all bugs I encountered in xrandr were related to
cloning. The radeonhd driver uses cloning.
