I have been running FreeBSD 4-STABLE and higher on SMP boxes reliable.
Those were 2 CPU boxen.  For more CPU's see LINT's options:

# Mandatory:
options         SMP                     # Symmetric MultiProcessor
Kernel
options         APIC_IO                 # Symmetric (APIC) I/O

# Optional, these are the defaults plus 1:
options         NCPU=5                  # number of CPUs
options         NBUS=5                  # number of busses
options         NAPIC=2                 # number of IO APICs
options         NINTR=25                # number of INTs

4 Gigabyte is currently the limit.  Peter Wemm [[EMAIL PROTECTED]] is
current working on getting 8 Gigabyte supported and working.
