Andrew,
You could probably test it out by having another primary
drive and install 
FC4. Then back that up on to tape, then boot up FreeBSD then
chroot in to 
the Linux emulation area then untar the FC4 install on top
of the emulation. 
It's a good theory but I'm not privy to the inner workings
of the how's and 
why's of linux emulation on freebsd.
