Ok, seems that I have the same problem in Ubuntu Hardy Heron.
Firestarter hangs up in the system boot, and when X starts reports me an error "no wireless interface found", so... I have to remove firestarter to do a "normal" start.
I have the files S40networking and S65 Firestarter... so firestarter starts up after networking, isn't it?
Anyway... I decided to use another firewall until problem is solved.
