Run "disklabel -B ad0" (substitute another disk for ad0 if 
appropriate.) You can do this now or after installing linux, it 
doesn't matter.

When you install linux, tell LILO (or Grub, or whatever) to install 
in the MBR of the new linux disk (probably /dev/hdb, but of course 
I don't know what you've got set up here). DON'T put it in the MBR 
of the FreeBSD disk (unless you want to use LILO to boot FreeBSD 
instead). LILO doesn't need to know about FreeBSD, only linux.

There's no configuration of boot0 (the FreeBSD boot loader you 
speak of) needed; it's smart enough to automatically give you the 
choice between 'FreeBSD' and 'other disk' (which will transfer 
control to LILO to boot linux).
