I just updated my ports tree and I'm now running virtualbox-ose-3.1.6_3. 
My problems persist.

You're definitely doing something different with your pxeboot compared 
to me. Take a look at the following screenshot of my vbox trying to 
pxeboot and compare to yours:

A lot of the text after the "Starting the BTX loader" line is different 
in my case to yours.

The pxeboot I'm currently using is from today's 8-STABLE, which I built 
by doing a "make buildworld buildkernel" and then copying the 
/usr/obj/.../sys/boot/i386/pxeldr/pxeboot binary to my tftp root dir.

Questions:

- What version of FreeBSD and arch (i386 or amd64) are you running on 
the underlying vbox host?

- Can you please check your /etc/make.conf and /etc/src.conf for any 
changes that might affect how the pxeboot binary gets built on your 
build machine?

- Can you please put your pxeboot binary somewhere for me to download 
and try?

Cheers,
