swsusp2 support requires a modification to be done to the initrd in a Fedora system. The exact procedure for doing so is at http://softwaresuspend.berlios.de/FAQ-6.html#ss6.4. The included patch modifies mkinitrd to have a --swsusp2 option that obviates having to modify the initrd manually.

We don't ship swsusp2, so this would add an option that doesn't work with the distro.
