PowerBook Password Security: Use With Partitioned Drives

I have a PowerBook with an internal hard disk that has been formatted into four partitions. I would like to use the PowerBook Password Security control panel to implement password protection. Can I do this on a hard drive with multiple partitions?
Apple Computer does not recommend using PowerBook Password Security on a hard drive with multiple partitions. This is because only one of the partitions will be secure if someone starts the PowerBook up from an alternate source, like a floppy disk or CD-ROM disc.
