anyone with physical access to your computer can do that with a Linux-cd too

afaik Knoppix mounts partitions by default read-only if you use the icons on
the desktop (take a look at the /etc/fstab), but if you manually do :
a) sudo su -
b) mount /dev/hda1 /mnt/hda1
it will mount it read-write (!)

an example (with /dev/hda1) how to mount a FreeBSD-slice from Linux :
mount -t ufs -o ufstype=44bsd /dev/hda1 /mnt/FreeBSD

you should find out which slice in FreeBSD has the info you'd like to see in
Linux

maybe it's interesting for you to look at disk-encryption in either 
FreeBSD or Linux, there's a section about it (for 5.x ?) in the FreeBSD handbook :

http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/disks-encrypting.html

but of course you can start putting a password for the BIOS after disabling 
booting from cdrom and floppy (network etc.)
