fglrx will not load: KCL_AtomicTestBit

[grutz]

Hey guys, I'm having a terrible time trying to get any fglrx driver to install on my Tyan FT72-B7015/S7015 system. Hopefully somebody else has seen this or can pinpoint to what's up. The host OS is Ubuntu 12.04.2 LTS Server and I've tried the 13.1 and 13.3 beta AMD drivers.

Hopefully it's something I've just missed or messed up during the installation. Pretty bare bones / followed the wiki / not much going on here!
