Ah, but do you? You have a need, scratch it! Why wait for someone else?

OOI: why would freeswan or usagi need to mess with the scheduler?

After you've successfully booted, have an init script do one of:
*) swap /boot/grub/menu.lst for a 'safe' version
or
*) edit menu.lst's 'default=' variable to point to the known good
kernel's entry
Then do the reverse on a 'good' shutdown.
