Great.

Just a couple of warnings I should have given before :)

- Do not try other password protected commands without knowing exactly
  what they do.  There is a good reason for the password... Bricking the
  module is certainly possible.

- Do not attempt the above procedure in any direction if your module was
  bundled with a laptop.  The OEM should set a new password in this
  case, so the above won't work.  But OEMs do all sorts of weird stuff,
  and I wouldn't be surprised if some of them implement a BIOS whitelist
  *and* don't change the MC7710 OEM password. This will be fixable, but
  the fix may require you to remove the module from the laptop and use
  another PC to change it back.
