Creating a swap partition is a part of the standard install IIRC. Also, this can be a swap file and does not need to be a separate disk (though I don't know if the installer handles this properly or not). Having said that, I don't have an issue saying that the minimum to run Xubuntu is 512MB at this point. Even at 512MB, swap will be needed, but I don't think that's a problem.
