Few!?!? Just off the top of my head:
- TSO (Tcp Segmentation Offload)
- efficient (no copy) TCP sendfile support
- Multiple MSI-X interrupt vectors (enabling RSS)
- Multiple Transmit Queues per NIC
- 64-bit kernel
- Usable ZFS support
- Dtrace works on loadable kernel modules
- usable support for non-x86 / ppc arches
- Local Crashdumps & "mini-dumps"
- Linux binary compatibility
- User controllable CPU affinity for processes and IRQ vectors
That's not exactly a huge list. Out of curiosity… how many of those
It represents a huge amount of missing functionality that Darwin
is missing, and most of other *nixes have.

You seem to be under the (common) misconception that FreeBSD and
Darwin share kernel code. For the most part, they do not.
Implementing MSI-X support in Darwin would be totally different
than in FreeBSD, for example.

If I knew (which I do, since I'm an ADC member, and have been running
the 10.6 seeds) I could not tell you due to NDA.
