After a bit of googling, it seems that logitech are being miserable with regards to this and other users have complained about the lack of this functionality in their mouse options panels. Apparently the solution is to uninstall the logitech mouse software and use the default miscrosoft mouse software, where the option will be avaliable. I searched around for a bit to see if I could find a registry setting to modify the option, but was unable to find the correct one. Can anyone else more familiar with the registry help here? Otherwise, I suggest you uninstall the logitech mouse software and then disable the show location of my pointer option in the microsoft software. Unfortunately, most likely using the ms software you won't be able to access all the advanced features of your mouse because it has loads of buttons and whatnot, so after disabling the feature in ms's software, you could try reinstalling the logitech stuff. Oh, and I suggest you drop logitech an email asking if they've got any ideas also.
