So, I now have Ubuntu Hoary Hedgehog running!

I had trouble with wireless, spent an age trying to get it to work, and then sorted it by rebooting! Oh well.

Having mounted my old HDD read-only in a USB/Firewire caddy, it is so far running well for me to copy content off. Now need to just copy apps across and get on with some real work.

And for those that are wondering, Hoary feels much nicer than Debian Sarge. Works better too. It was worth the effort, and the expense on the additional HDD that I used to make it easier to manage.
