Just wanted to talk about dual hyperthreaded CPU's. I have a dual xeon HT machine on FreeBSD. When compiled with SMP options and enabling the HT sysctl the machine runs with 4 logical CPU's. Which drop the overall CPU usage significantly and it works very well. This has been my experience with hyper threading and FreeBSD.

utilize dual CPU's.
hlds_l and srcds do not support multithreading, nor does FreeBSD handle dual processors on behalf of the Half-Life processes.
Also, as Steven commented, there is no way to specify which CPU a process will run on.
As a result, all processing would always take place on CPU-0.

Not true. The OS can be smart enough to see that one cpu is idle, where other is not, so new processes can be started "automagically" in idle cpu.
There's a 3rd party tool for linux who do some processor affinity, in http://www.ccur.com/rt_oss.asp . Not tested for game servers, but some other apps (apache/sendmail) works quite well.
