Well running bitcoin-qt in the -gen mode will not mine for you. You need an external program like cpuminer. This will then be able to connect to bitcoin-qt and submit blocks.
What? Why else would I be getting 100% on all four cores? When I'm not -gen it uses about 2%.

How could I connect minerd to bitcoin-qt?

I don't know why you are getting 100% but -gen just tells bitcoin-qt that it will be for mining and to get the work for it.

I've been mining on the testnet with my CPU at 3 megahashes per second for over 8 hours, and I haven't gotten a single block. The difficulty is at 1.0 90% of the time, and according to a mining calculator, I should be getting just over 2 blocks an hour with difficulty of 1 and 3M hashes/second. Am I just having extraordinarilly bad luck, or could there be some kind of issue? I'm mining by running `bitcoin-qt -testnet -gen`, and bitcoin-qt is using 100% CPU on all cores.
