My advice, Rowan... - back everything up that you need (probably only /home/rowan or whatever) - re-install from a fresh Ubuntu CD.
Trying to work out what's going on with this one just seems to be taking up time of yours that you really do not have... the truth is that Ubuntu is VERY good these days at detecting hardware and you will probably end up with a much more stable system by taking an up-to-date Ubuntu and installing that.
