Thanks everyone for all the great suggestions and things to explore.
I do remember now that some older Mac G4 towers we used (running Mac OS X server) had a similar headless problem and plugging the DVI to VGA adapter in the back sorted it. I had forgotten about that so it might be the answer as the discussions on those links suggest.
As far as what happened at the point where the Mac Mini was on but not visible on the network I'm not sure what stage it was at. As I mentioned this is in a remote office so I'm troubleshooting it via email and phone with a non technical person but I'll check if they actually plugged the screen in at that point and what they saw if they did.
I'm new to Ubuntu on a Mac that isn't running in VMWare to be honest. I'm not sure if I'm using Bootcamp. We booted from an Ubuntu CD we had downloaded and chose the option to overwrite the whole disk. I don't believe there is any Apple software on the disk but I must admit I'm not really sure how the installer does it.
