@Aaron, could you use pyrit or any other OpenCL tools with yours HD6850 without lockup?
I get the same error from pyrit (cpyrit-opencl) as you do:
awatry@veer:~/src/opencl_applications/cpyrit-opencl-0.4.0$ pyrit benchmark Pyrit 0.4.0 (C) 2008-2011 Lukas Lueg http://pyrit.googlecode.com This code is distributed under the GNU General Public License v3+
Calibrating... LLVM ERROR: Not supported instr: <MCInst 206 <MCOperand Reg:1046> <MCOperand Reg:1031> <MCOperand Imm:0> <MCOperand Imm:0>>
I'm not sure right now what instruction is causing that error.
I do get lockups when I run: bfgminer -v1 --benchmark

A simpler test case might be the piglit min() builtin CL test. Does that test lock up for you as well? You might have to run it a few times.
