Intel X540 driver on pfsense 2.0.3 AMD64

[giuxtheone]

Hi all!
I'm trying to get drivers for new network card with chipset intel X540 on pfSense Stable 2.0.3 ! I tried also downloading drivers from intel and trying to compile on FreeBSD 8.1.
Has anyone ever tried to compile it, or driving me to the right direction? (it stops compiling on the first .c file with a simple Error Code 1…)
2.1 does correctly see the network cards on the system, but it has some strange behaviour on my Orcale X3-2 Server

Thank you for your precious help
