for FreeBSD 6.3-RELEASE you might try something like

Installation FreeBSD 6.3-RELEASE xen

Hardware
x86 Pentium 4 1.7 GHz, 1 GB RAM
dom0 on minimal 2GB Compactflash (OpenSUSE 11.0 e.g.) using 256 MB dom0 
memory
a couple of harddrives

Installation procedure
- do fresh installation FreeBSD 6.2 on harddrive ( chosen to install 
everything)
- login into system and do
- cd /var/tmp
- svn co http://svn.freebsd.org/base/projects/release_6_3_xen/ 
release_6_3_xen
- mv /usr/src /usr/src.ORG
- mv /var/tmp/release_6_3_xen /usr/src

then usual make world
  cd /usr/src/sys/i386/conf
  cp XEN <hostname>
  cd /usr/src
  make buildworld KERNCONF=<hostname>
  make buildkernel KERNCONF=<hostname>
  make installkernel KERNCONF=<hostname>
  make installworld KERNCONF=<hostname>
  the installed xen kernel will not boot, use kernel.old instead

- cp FreeBSD xen kernel from /boot/kernel/kernel to dom0 partition
- create xm config file <xen-configfile> using vi

  xm create -c /etc/xen/<xen-configfile>
 

The config above uses a physical harddrive ( Letter D: or /dev/sdc in 
Linux syntax). These instructions should serve only as a guidance, and 
contain probably errors as it is just a quick writeup.
