* Add debian/patches/41_revert_sg_io_eperm_failure.dpatch:
    - Between 2.01+01a01 and 2.01+01a03, upstream changed the behaviour of
      SG_IO ioctl()s failing with EPERM; earlier releases ignored it, while
      the current one aborts the program. While in principle, EPERM checking
      is a good thing, it breaks burning for non-root users, so revert this
      test for now.
    - See also http://bugs.debian.org/374685.
