Why you want local X-server ? Remote one would work via Xvnc.

****************************************
1. Work with PVOPS kernel via VNC
****************************************
1.Install Ubuntu Desktop via tasksel
2. apt-get install vnc4server
3. su - user1
4. vncserver
5. Modify .vnc/xstartup to run /usr/bin/gnome-session and comment out xterm
6. Modify /etc/rc.local
   export HOME=/home/user1
   vncserver :1 -geometry 1280x1024 -depth 16
   exit(0)
7.Reboot into Xen Dom0 with PVOPS kernel
8 Connect via remote desktop :-
   vncviewer IP-Dom0:1

Would you have problem with network switch install light weight X-windows
system . Details here:-

http://bderzhavets.wordpress.com/2009/05/30/light-weight-x-windows-system-for-xen-3-5-unstable-dom0-on-top-of-xubuntu-9-04-server/

This link is good only for X-windows setup in meantime ( UDEV patches are
already in xen-3.4-testing.hg , so the rest of blog is outdated )

***********************************
2. Try Andy's 2.6.29.4 patch set
***********************************

Andy is doing very good job. However, it wouldn't be acceptable
for production, unless Suse would decide to support him :( .
Andy is trying to rebase every next Suse's src rpm for vanilla on his own.

Citrix will be always behind PVOPS kernel. That's a point

I've been trying for several days to get a xen dom0 booting as
described on Boris Derzhavets blog.

I have been able to boot Jeremy Fitzhardinge's pv_ops kernel under
xen, but my X server wouldn't start so I've been trying to get Andrew
Lyon's rebased opensuse patches to work.

I have asked for help in the freenode ##xen channel but they haven't
been able to solve anything. I did find another person experiencing
the same problems as me though.

I've recorded the boot process on a camera so I could see what was
happening as it was so quick. When I boot the 2.6.30.1 patched kernel,
it gets up to "Scrubbing Free RAM:..." then reboots. I've tried
booting with the noreboot option, and the screen goes black when it
reaches "Scrubbing Free RAM:..."

It has been suggested to use a serial console to debug my problem, but
I don't have access to a pc with a serial port.

Attached is my kernel config, and below is the output of cpuinfo and
lspci. Let me know if there is anything else I can provide to help.
