What happens if you switch around the pci ids in xorg.conf, say to make 6:0:0 correspond to Device[0]-0? You can get the order linux believes the cards are in using,

Code:
cat /proc/ati/?/interrupt_info

I installed from stage 3, so after I got kde emerged all I had left to do was the following (I omitted the aticonfig step b/c I copied the xorg.conf over from my 5830 box).

Code:
emerge ati-drivers cgminer      (this pulls in opencl and amd-adl-sdk)
eselect opencl set X       (where X is the # corresponding to ati)
aticonfig --adapter=all --initial

Here's my xorg.conf, though I don't see any huge differences between ours.

Code:
