One final thing to note, some of the boards really "cut corners" on the
on-board Gigabit Ethernet (GbE).  A few I saw connected the 8254x to the
legacy 32-bit at 33MHz PCI bus, instead of the PCI-X bus (especially those
that use the 32-bit PCI-only 82541) or PCIe in the case of the 7230.
Those will _kill_ your PCI I/O at GbE.

A few of the 7230-based boards did it "proper" and put in a BCM572x or
8257x PCIe NICs on their own, dedicated PCIe x1 or x4 channels.
