I haven't tried pushing large volumes of traffic through them (yet), but I use
Pro/1000MT Quad Port Server Adapter cards in several OpenBSD 3.6 systems,
detected as "Intel PRO/1000MT (82541EI)".  No errors, no instability.
All are PCI-Express cards in Dell PE650 and PE1750 systems, I do need to
go back and double check that they are in the correct PCI-X slot.

Card specs:
   MM:849858
   PCODE: PWLA8494MT
   Version: C14926-001

(P.S. I would include a dmesg, but we're running a custom kernel, to
address an unrelated issue.)
