Following Ians suggestion I will summarize again, what I've written in
the bug report.

Passing dom0_mem=max:4GB to the hypervisor works around the issue. That
is, the dom0 with underlying hypervisor does boot. Please see
http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1698#c4 for a
full dmesg/xm info output.

The relevant part is:

node_to_cpu            : node0:0,2,4,6,8,10,12,14
                         node1:1,3,5,7,9,11,13,15
node_to_memory         : node0:21765
                         node1:24425
node_to_dma32_mem      : node0:0
                         node1:1969



Moreover my company is willing to pay anyone who fixes this bug a
symbolic fee of 1000 EUR as thank-you for letting us making use of Xen;
either personally to the contributor or to a (non-profit) organization
of the contributor's choice.
