Rikkert, Please check the MEG reference documentation. On page 30 it is mentioned that the dipole positions are indeed by construction not regularly spaced. If you want to have them in normalized space you will need to replace the subject specific source positions with the corresponding positions of the template sourcemodel. The templates can be found in the template directory of the megconnectome software.
