 I currently have one -CURRENT machine, and several 6.2-STABLE machines.  
 For at least two of them (the -CURRENT and an x86 -STABLE machine) I'd 
 really like to have WoL support, as these are my workstation and a home 
 server, both of them really do not need to be on all the time, but I 
 want to be able to reach them when I need a file from them when I'm

 I usually use either if_em or if_xl chipsets, so I hoped landing this 
 code in at least -CURRENT (should go there first, I guess) would result 
 in more chipsets supported ;)

 I don't run Linux on either machine.  Perhaps I could do some tests on 
 my workstation with a CD-based linux distribution.
