Would this system work correctly with FreeBSD 5.3 ?

You're asking a possibly bad question.

First, FreeBSD 5.3 will run on a quad opteron system.  The tyan
quad motherboard supports upto 32 GB on memory, and FreeBSD 5.3
should/will use all 32 GB.  So, your 4 GB is no problem.

Second, HTT may or may not cause a small impact on performance.
It depends on what applications you run.  Of course, my opteron
processes don't support HTT

  CPU: AMD Opteron(tm) Processor 248 (2193.43-MHz K8-class CPU)
  Origin = "AuthenticAMD"  Id = 0xf58  Stepping = 8

Third, what OS have you run that you have never experienced a crash?
If your electricity goes out, you'll have a crash.  If your hard drive
dies a (un)natural death, then you have a crash.

Linux-compat for 32-bit applications works.  But I must ask, you're
purchasing a quad opteron system to run games?
