I'll have to test when I get back home and have access to server
hardware.

Looking at our current initscripts "/etc/init.d/networking stop" gets
called in rc0.d which will call ifdown and ultimately do the "ifconfig
ethX down", unless the interface isn't defined in
/etc/network/interfaces.

So maybe we have a race somewhere and the interface doesn't reliably get
brought down on shutdown, causing this bug.

We can't call ethtool as it's not shipped by default in Ubuntu and certainly 
won't introduce it in an SRU.
Also, based on what I remember about that specific call and somewhat confirmed 
by the manpage entry, "wol g" actually turns on wake-on-lan ignoring the BIOS 
setting which we certainly don't want to do.

So what we want is for a machine where the BIOS is properly configured
and supports wake-on-lan to actually wake up on magic packet but not
make every single Ubuntu system suddenly boot when they get one ;)
