Hopefully take care of FS#7806 - Current Sansapatcher fails to boot OF by removing all hotswap support from the bootloader. It won't fully be closed until Sansapatcher is updated of course. There's still a report of the partition dump not working unless 20 bytes of padding are inserted at the start of main() but that's only a developer-enabled feature. Seems weird though.
