Which Intel Gigabit PCI card has native support in 10.5.x?

[scalar]

I've got a machine with dual onboard 82757EB Intel NIC's that haven't ever worked under OSX, so I've been hobbling along with an Intel Pro/100 PCI card for several years now as I had found a working kext for it under 10.5.2 and had the card on hand. However lately the card has been giving me random fullscreen lockups & occasional KP's (my onboard ALC883 has been doing this as well btw) so I am wondering what Intel NIC's are supported in Leo 10.5.x (10.5.8 preferred) natively?
