Would this system work correctly with FreeBSD 5.3 ?

There are no heat issues, and the pin-out is identical to single-core
Opteron CPU's -- 940-pin.  Dual-core CPU's work just fine in AMD's Quad
reference machine.

What he is saying is that Tyan put all the PCI-X & PCI controllers on a
single HT "chain" off of the BSP.  A better design, such as the HP DL585,
connects its PCI-X controllers spread out over two CPU's (using HT
links).
