I upgraded to SDK2.4,  I don't think that helped with mining but it fixed some aticonfig stuff.

I updated my poclbm command line

./poclbm.py -d0 --host=btcguild.com --port=8332  -v -w 256 -r 10 AGGRESSION=12 BFI_INT > /tmp/gpu0&
./poclbm.py -d1 --host=btcguild.com --port=8332 -v -w 256 -r 10 AGGRESSION=12 BFI_INT > /tmp/gpu1&

I'm now overclocked to 950Mhz and running 333MH/s/GPU @ 97% GPU

One 6970 was DOA so that will be swapped out on Monday, hopefully my power supply can handle all 3
