If its the virtual framebuffer bits, then they're populated in a couple
of places

tools/python/xen/xend/server/vfbif.py

sets up the basic node & permissions. While in PV case, the daemon like
/usr/lib/xen/bin/xen-vncfb (or xen-sdlfb) populates the rest. Can't say
offhand where the info would be populated in the HVM case since this code
changed fairly recently & i've not checked up on its new workings.
