Boot into your linux box, edit /boot/grub/menu.lst
And add the following lines:

title FreeBSD
root (hd0,1)    # this changes based on where on the partition/drive
the FreeBSD is installed.
chainloader +1
savedefault

run,

# grub-install /dev/hda      # sda if sata disk

reboot.

this should help to solve your problem
