you can run X within the guest directly. upgrade to 3.0.4, edit Config.mk to change XENFB_TOOLS to =y and do a make-install tools. This'll give you the dom0 components for accessing the framebuffer. compile a domU kernel with framebuffer support in (it's selectable in the kernel menuconfig). If you want to be able to run virtual terminals on the framebuffer, you'd also need to select the generic Linux options for the framebuffer console. I'd recommend you do this. domU: /etc/inittab S0:2345:respawn:/sbin/mingetty ttyS0 domU: /etc/securetty or /etc/securettys (whichever you have) domU configfile: "xencons=ttyS0 console=ttyS0 video=xenfb" domU configfile: "vfb=['type=sdl']" to get a local display of the domain's framebuffer or vfb=['type=vnc'] or "vfb=['type=vnc,vnclisten=ipaddr']"
