You have to mount linprocfs -- but there is a bug in the cpu features of 
linprocfs not returning SSE2, even if it is present. Compare the output 
of the following and see:

/usr/compat/linux/bin/cat /proc/cpuinfo
dmesg | grep Features

Thus, you have to patch the matlab scripts to ignore that check.

I have recently installed matlab2008b on FreeBSD 7.2-RELEASE changing 
the following in bin:

In ldd and mexext: Linux) -> FreeBSD)
In matlab: #!/bin/sh -> #!/usr/compat/linux/bin/sh
In mbuild and util/oscheck.sh: Add an 'echo 1' line after the 
cpuinfo/sse2 line.

Basic functionality is there. Maybe more similar changes are needed.

Cheers,
Jan Henrik
