Assuming you pass the event to the popup function 
event.x_root and event.y_root should be what you want:

Here is my popup menu maker (can't remember where I stole this one from!!!)

    def makePopUpMenu(self, items, event):
        menu=Menu(None,tearoff=0)
        for item in items:
            if item == 'seperator':
                menu.add_seperator({})
            elif type(item) == ListType:
                for num in item:
                    menu.entryconfig(num, state=DISABLED)
            elif type(item[2]) != ListType:
                menu.add_command(label     = item[0],
                                 underline = item[1],
                                 command   = item[2])
            else:
                submenu = self.addMenuItems(menu, item[2])
                menu.add_cascade(label     = item[0],
                                 underline = item[1],
                                 menu      = submenu)
        menu.tk_popup(event.x_root,event.y_root,0)
        return menu
