Looks like you stopped reading before you got to the part about dhcpcd. 
  It's possible to tweek it's config to not over write your wanted 
config as well... it's just doesn't appear to be as versatile.
Also it doesn't HAVE to come from a power outage, all you have to do it 
get disconnected for a few seconds.  It just usually comes from a power 
outage around where I'm at... which doesn't happen very often, but if 
the battery backup thats on the cable modem doesn't last as long as the 
one on the computer than I'm hosed.  I usually have to reset the network 
to get it to grab another, which is always the same, IP, or I'm not 
going anywhere.  I probably need to get a script going in cron like I 
used to have on a firewall at work that has buggy ethernet drivers.  It 
just reset the network whenever it didn't succeed in 3 pings to various 
locations.  Worked well till I got a 2.4 kernel on there that fixed the 
problem properly :)
