random key is encrypted with RSA and stored in the header, RSA private
key is (encrypted using the password at installation time) is also
stored in the header.
At resume the password is used to unlock the private key which is then
used to decrypt the random key.

What's "shift"? swap-offset prints the offset in PAGE_SIZE units, so
you must multiply it by 4096 to get a byte offset. Furthermore the
swap signature is at the end of the first page.
So you'd do:
shift = swap_offset_number * 4096 + 4096 - 10 (10

Then maybe split s2ram.c into s2ram, s2ram-x86.c and s2ram-ppc.c; this
will ease the addition of a new platform.
