Intel PRO/1000 PT wake on lan not working

[bigwolf]

I have installed Intel PRO/1000 PT network card into my HP N40L with installed NAS4FREE. I would like to get WoL working but it is not. I have enabled wake on lan in BIOS.
Version of NAS4FREE: 9.1.0.1 - Sandstorm (revision 531).

There isn't WOL_UCAST,WOL_MCAST or WOL_MAGIC in the list of network card capabalities... but the NIC should have driver support in the FreeBSD, see.

Can you help me? I am not very familiar with FreeBSD. I have tried to search more info but with no luck...
Any help would be much appreciated.

Edit: I have been playing with my server and found out that even if the wake on lan is enabled in BIOS the Intel NIC is cut off from power after the server is switched off. I can't find any option in the BIOS to enable power to PCIe after shutdown...
