I selected 'None' then 'Extra', compiz is now enabled automatically when I log in. Evidentally the upgrade switched a flag somewhere.

There is a minor caveat to this - the apearance dialogue will change some of your advanced desktop features settings, which is annoying but easily fixed. I'm sure there will be a simple config file flag which can be changed instead of this - anyone know where it lives?
