I'm on 7.2 STABLE.  man (8) ifconfig mentions wol, so the capability at 
least exists in 7.2.  In grepping through the device sources, it looks 
like the e1000 driver has wol capabilities enabled as do a couple of 
others.  You may be able to use that code at least to get headway in 
creating drivers, if you can't use those existing drivers.  If you're 
using the e1000 driver already (I believe you mentioned you're running 
Intel NICs), you may be able to use wol out of the box without making any 
changes.  Seems worth testing at least.

obvious, my opinions are my own
