What are some http mining pools out there? The open source FPGA miner with source available at https://github.com/progranism/Open-Source-FPGA-Bitcoin-Miner does not support stratum, so in order to test it, I need an http pool. Are there any left?
Sounds like you need to use getblocktemplate. If you do an http POST to http://gbt.mining.eligius.st:9337 with a body of: 

{"id": 0, "method": "getblocktemplate", "params": [{"capabilities": ["coinbasetxn", "workid", "coinbase/append"]}]}


You should get a transactions to process. See https://en.bitcoin.it/wiki/Getblocktemplate for more information. 

I can't find many other sites that support GBT but there is a list of compatible pools in the above link as well.
