modprobe.conf module writing

There's one last issue with this.  coldplug is correctly identifying 
that a chipset requires ndiswrapper, but it is setting ndiswrapper as 
eth0.  IMO any ndiswrapper nics should come at the end of the ethX 
chain.  It's causing problems on 2nd and third boots because the other 
nics end up getting mis-loaded as the wrong devices.. so the configs 
aren't executed properly.

We should also make sure we're making use of the HWADDR= line in the 
files, by adding the MAC address.  This prevents the race condition we 
have all discussed a number of times.
