It is possible, but you need to write a shell or perl script to combine
the user entries in the Linux files /etc/passwd and /etc/shadow to one
file having the FreeBSD /etc/master.passwd format. Then you will have to
append your file to /etc/master.passwd an to run pwd_mkdb to build the
data bases.

I would NFS export the home directories on the Linux box and mount them on
your FreeBSD system. Then you can copy all the files with tar:

tar cCf /path/to/nfs/mount - . | tar xvpCf /path/to/new/home/dirs -
