It did seem low to me as well. Here is the status after running
1.7.9-jumbo5 with MPI for 1hr executed with:
mpiexec -np 6 ./john --incremental /home/dlaporte/hashes
guesses: 0 time: 0:01:00:00 0.00% c/s: 17570

Here is the status after 1hr with 1.7.9-allopencl-04 executed with:
./john --incremental /home/dlaporte/hashes
guesses: 0 time: 0:01:01:10 c/s: 66062
It's an HD5830 with a Phenom II X6 1055 and 16GB RAM running Fedora 16
(x86_64). I'm using AMD-APP-SDK-v2.6-RC3-lnx64 and the 11.12 driver.
Does these numbers seem in-line with what I should expect?
Thanks for the "unique" tip, I'll try optimizing everything once I get
this figured out.
