Linux needs its own bootloader - GRUB and Lilo are the usual options. 
GRUB (in the BSD ports) can also boot all your other OSen.  However, it 
takes some education to configure correctly.  If you want to use GAG or 
the FreeBSD bootloader, then install GRUB or Lilo to Linux root, *not* 
to the MBR.  (The installer for your Linux distro should have an option 
for this.)  GAG or the FreeBSD bootloader will then make GRUB or Lilo 
boot Linux.
