I tried it last night, although it and apparently most other things hate 
the alc0 interface.

Eventually it seemed like an NFS server would be useful, and pxeboot 
will start a FreeBSD livefs.  But only directly, entering FreeBSD's 
pxeboot as the filename in DHCP.

With grub4dos
   title FreeBSD
   pxe keep
   chainloader --raw (pd)/images/freebsd/boot/pxeboot

it loads pxeboot, but then:

netboot: couldn't probe pxenet0
pxe_open: netif_open() failed
...
can't load 'kernel'
OK

So it loads pxeboot, but then pxeboot can't use the pxenet0 device.
