Applying Debians 04-unaligned-memory.dpatch from Khalid Aziz

<khalid_aziz@hp.com> to fix dosfsck unaligned memory accesses:

  * Fix unaligned memory accesses which cause warnings to appear
    everytime the elilo bootloader script runs. This has led a number of
    users to believe their install has failed (Closes: #258839).
