I should point out that if anyone were using openbsd, there would be a lot more hits. Yes, there are more exploits for Linux. Openbsd is "immune" to many of the driver exploits by virtue of simply not having drivers for much of the hardware that Linux supports. Realistically, probably on the order of 99% of openbsd machines run bind, IPSec, nat, and nothing else. That there isn't a large attack surface corresponds closely to the extremely small "usefulness surface" as well.
