228 Mh/s is definitely not coming from my GPU, but it's pretty measly for my miner. (It's supposed to do ~700 Mh/s.)
All this makes me tempted to believe what a friend suggested to me: maybe I need to install different firmware. This goes along with a topic from the BFL support forums where the problem was caused by using the Auto-Tune firmware. Apparently, Auto-Tune doesn't always get it right.
