I'm not sure UML would help you here. I think you'd be better trying to
run Apache in a chrooted environment, PHP and PostgreSQL included. You
don't need another kernel, but another set of libraries.
BTW, I think UMLSIM (umlsim.sf.net) could help to play the
"unplug-the-server" game. In theory you could rewrite the block
subsystem to "fail", simulating a real disk failure and possible a
system shutdown. I don't have time to do it myself right now however ...
