I found some resources, which might be useful to answer this question. As far as I know, FreeBSD uses a Multilevel feeback queue and Linux uses in the current version the completly fair scheduler.

Also found a nice link with regards to the new Linux Scheduler for those interested:
http://www.ibm.com/developerworks/linux/library/l-scheduler/
<br />It is also referred to as the O(1) scheduler in algorithmic terms (CFS is O(log(n)) scheduler). Both have been in development by Ingo Molnár.
