Wow, this wasn't my experience at all. At my previous employer we
used Intel EEPro 1000 Server cards with the em(4) driver on FreeBSD
4.5 with nary a hitch and excellent performance. This was on
ServerWorks chipset motherboards with P-III and P4 processors.

The follow-on to the Tigon II is the Broadcom BCM570x supported by
the bge(4) driver in FreeBSD. This is not what you want. They're
certainly cheap to test with, though; the Netgear GA302T sells for
under $40 at a few online retailers.
