In case you have not got it working yet, I can offer a glimmer of hope 
by telling how I managed to multi boot Linux and FreeBSD on MBR logical 
partitions.

By using the grub patch at:

<http://www.freebsd.org/cgi/query-pr.cgi?pr=158362>
ports/158362: sysutils/grub [patch] allow GRUB to boot FreeBSD from an 
extended partition

You must rebuild and reinstall grub (from Linux I guess).

My install is fairly old and from the days when sysutils/grub at least 
was installable from within FreeBSD i386. The patch itself does not 
touch FreeBSD sources, only grub. So I expect it will build from any 
OS/machine that can build grub.

When installed I can boot FreeBSD from an MBR logical partition like so:

title           FreeBSD CURRENT (amd64) (disk1, logical partition s11)
root            (hd0,10,a)
kernel          /boot/loader
boot

Depending upon how recent version of FreeBSD you have installed you may 
have to config the FreeBSD loader to find its root file system. 
10-CURRENT should be okay.
