Yes, but I'm trying to use Intel's driver at this point (since the stock 
7.2R em driver, as stated, does not support WoL yet):

http://downloadcenter.intel.com/filter_results.aspx?strTypes=all&ProductID=1938&OSFullName=FreeBSD*&lang=eng&strOSs=52&submit=Go!

And it does appear to offer support for WoL.  They (Intel) have 
functions in their if_em.c source file that sets up the WoL.  However, 
there is no IFCAP_WOL define in Intel's code, so maybe it does not 
interface with ifconfig correctly at this point?  I don't know.  I was 
hoping to get some pointers on where to look or how to tell.  Also, I'm 
not opposed to adding the WoL support - I'm not too bad in C - I've just 
never written a FreeBSD device driver and the excellent post by Stefan 
Sperling (referenced from the WoL wiki) seems to be too far out of date.

The wiki itself states: "Note that the obsolete ioctl-based 
configuration approach is discussed there, but ifcaps should be used 
instead."

So, not knowing anything about either ioctl-based or ifcaps config, I 
can't find any resources on how to get started in the right direction 
(hence my post to hackers).

Also, if Intel's driver code works, it seems to me that it makes more 
sense to use their code for em devices, no?  Is there a copyright 
problem with that?
