I tested a handful of kernel versions, and it looks like this is indeed the case. As far as I can tell, this problem was introduced between 2.6.19.7 and 2.6.20.
Looking at the diff between those versions, it looks like there were some noteworthy changes to the SMP balancer. I'm still working on narrowing this down further.
