Dorking around with solo mining on a spare rig and it never accepts any hashes even though it is running full tilt.

Ignore the low hash rate, I haven't optimized the client with flags yet. Yes I know that that'd likely take years to find a block solo these days.
Running a Phoenix 2.0 client and connected to Bitcoin-qt v0.8.1-beta running in -server mode that has downloaded the full blockchain.
Where have I gone wrong?
