Well, on my linux box (slackware) fdisk is not even on the $PATH for a non-root user.
(I think that might be good ;-) And if you try /sbin/fdisk -l as ordinary user
you'll get access denial ("can't open") on /dev/hdxxx etc.

You might want to try something like

    import os
    print os.popen('mount').read()

and see if parsing that would be useful. Or if you want to look at
non-mounted possibilities, perhaps

    print open('/etc/fstab').read()

will show something interesting. There are man entries for both mount and fstab, but
it's a lot of reading ;-/

Neither of the latter require su, AFAIK.
