Update!

I've successfully installed Linux Catalyst 15.7 drivers on the PIMP mining platform adapting the instructions located here: https://www.reddit.com/r/getpimp/comments/294uie/add_amd_146_drivers_and_djm34s_optimized_sgminer/ and using http://www2.ati.com/drivers/linux/amd-driver-installer-15.20.1046-x86.x86_64.zip for the new source.

Happy to report I got my 6970 card hashing away at 1.8Mh with no hardware errors.

Time to tweak and get the max hash rates.

Thanks everyone for pointing me in the right direction!
