Which version of the univention drivers? Maybe the univention signed drivers 
are bit old.

Try one of:
http://www.meadowcourt.org/private/gplpv_2000_0.11.0.372.msi
http://www.meadowcourt.org/private/gplpv_2000_0.11.0.372_debug.msi
http://www.meadowcourt.org/private/gplpv_2003x32_0.11.0.372.msi
http://www.meadowcourt.org/private/gplpv_2003x32_0.11.0.372_debug.msi
http://www.meadowcourt.org/private/gplpv_2003x64_0.11.0.372.msi
http://www.meadowcourt.org/private/gplpv_2003x64_0.11.0.372_debug.msi
http://www.meadowcourt.org/private/gplpv_Vista2008x32_0.11.0.372.msi
http://www.meadowcourt.org/private/gplpv_Vista2008x32_0.11.0.372_debug.msi
http://www.meadowcourt.org/private/gplpv_Vista2008x64_0.11.0.372.msi
http://www.meadowcourt.org/private/gplpv_Vista2008x64_0.11.0.372_debug.msi
http://www.meadowcourt.org/private/gplpv_XP_0.11.0.372.msi
http://www.meadowcourt.org/private/gplpv_XP_0.11.0.372_debug.msi

and give it a go. I just tried it on 2003 and it works fine, or at least from 
30 seconds testing it correctly shows that of the 4G I assigned to the domu, 
only 787MB is free immediately after boot. If it still doesn't work, use the 
_debug version and send me the /var/log/xen/qemu-dm-<domu name>.log. You should 
see something like:

13005008537656: XenPCI --> XenPci_InitialBalloonDown
