You need to look at the Registry table, whose structure is described here:

http://msdn2.microsoft.com/en-us/library/Aa371168.aspx

In particular, the fields you need to look at are Key, Name,
and Value. Notice that Value is Formatted, so you may have to
expand the formatting first (looking at further tables possibly).

The rough sequence of actions would be

db = msilib.OpenDatabase(path, MSIDBOPEN_READONLY)
view = db.OpenView("SELECT Key, Name, Value FROM Registry")
while True:
  record = view.Fetch()
  if not record: break
  print record.GetString(1), record.GetString(2), record.GetString(3)

Unfortunately, GetString is not implemented yet, so it might be that
what you want to do is not possible yet.

HTH,
