Yes I have hardware - since March.
Everyone should note that difference of dual-core vs. single core doesn't
matter one bit for FreeBSD. We don't have NUMA support, which is what is
required to care about the difference between 1x dual-core & 2x
single-core (or 2x dual-core & 4x single-core) Opteron.
For 6.0-RELEASE (which branches June 1, 2005), I'm going to just have the
kernel ignore that dual-core Opteron sets the HTT feature flag.
