The code has definitely been broken for SCHED_ULE, which is a default scheduler. It may have been broken for SCHED_4BSD in more subtle ways, e.g. with manually configured CPU affinities and for interrupt devilery purposes. We still provide a way to disable individual CPUs or all hyperthreading "twin" CPUs before SMP startup. See the UPDATING entry for details. Interaction between building CPU topology and disabling CPUs still remains fuzzy: topology is first built using all availble CPUs and then the disabled CPUs should be "subtracted" from it. That doesn't work well if the resulting topology becomes non-uniform. This work is done in cooperation with Attilio Rao who in addition to reviewing also provided parts of code.
