For now I'm content with 'mount':

import subprocess, tempfile, re, pprint

tf = tempfile.TemporaryFile()
subprocess.Popen('/sbin/mount', stdout=tf)
tf.seek(0)
mountlines = tf.readlines()
tf.close()

reMountLine = re.compile('(.+) on (/[^\s]*)( \((.+)\))?', re.I)

mounts = []

for ml in mountlines:
     m = reMountLine.match(ml)
     if not m: next
     g = m.groups()
     type = 'unknown'
     modes = g[3]
     if modes:
         modes = modes.split(', ')
         if ((g[0].startswith('/dev/')) and ('local' in modes)):
             type = 'hd'
         elif g[1] == '/dev':
             type = 'dev'
         elif g[0].startswith('automount'):
             type = 'automount'
         if 'nodev' in modes:
             type = 'changeable'
             if 'read-only' in modes:
                 type = 'cd'
     mounts.append([g[1], g[0], modes, type])

pp = pprint.PrettyPrinter()
pp.pprint(mounts)


Greetlings from Lake Constance!
