My bad. I should have said:

class Disk(Folder):
  def __init__(self,driveLetter):
    Folder.Folder.__init__(self, driveLetter + ":/")

That was the first thing I tried, but because the libs were importing
each other, etc, it got hung up with wierd "This module doesn't exist"
errors, when it clearly did.
