Volker Ruppert 62a568c131 - changed license headers from LGPL to MIT for all devices / drivers that have
been ported from QEMU and originally have this license
- TODO: The QEMU people should verify the changes and tell us if something is
  missing. Bochs 2.6 will be released after everything has been confirmed to
  be okay.
