You can always bypass init and make the system calls yourself if you know it's 
safe.  I recently learned that the system call to initiate software suspend 
is a modified reboot call, ala:

reboot(LINUX_REBOOT_MAGIC1, LINUX_REBOOT_MAGIC2, 0xd000fce2)

I'm not saying this is a GOOD thing, just that it's doable.  (As root, 
anyway.)
