At this point, I can vnc in, but never get a display (the connection
isn't refused, but no graphical output either)

The config I'm using is:
kernel = "hvmloader"

builder='hvm'

shadow_memory=16

vif = [ 'mac=xx:xx:xx:xx:xx:xx, bridge=bridge0' ]

#'file:/usr/pkg/etc/xen/iso/FreeBSD-8.2-RELEASE-amd64-disc1.iso,hdc:cdrom,r'
    ]

boot="d"
