Ubuntu Hardy and suspend to RAM

The latest version of Ubuntu finally allows me to suspend to RAM so that I can quickly sleep my laptop or shut the lid and have it save power, starting up quickly again. Not only that but it also allows me to do that with the kvm modules still loaded. This means that I can have a number of virtual machines running and not have to worry about shutting them down befor putting my laptop to sleep. ( I might need some more RAM now!)
