The bug report Jan refers to, and an opensuse-virtual mailing list thread 
(mentioned in the bug thread) that announces dropping support for 32 bit on 
opensuse 12.1, can be found at:

https://bugzilla.novell.com/show_bug.cgi?id=732424
http://lists.opensuse.org/opensuse-virtual/2011-07/msg00001.html

Nowhere in these threads is it mentioned the technical reasons why 32 bit 
support has been dropped. In fact, one poster in the discussion mentions a 
lack of knowledge of any other distro that supports 32 bit xen. I can confirm 
that fedora 16 still has the i686 rpms. I'm going to assume that suse is just 
trying to lighten the support load for a package that probably isn't getting a 
lot of use on 32 bit.

But since 32 bit is all I've got on my suse machine, I went ahead and 
downloaded the .src.rpm for xen from the 12.1 repo, and recompiled it with 
minimal alterations to the .spec file controlling the compile and install. 
They indeed disable support for dom0, and a link at the end of the %prep 
section is needed to find the kernel-xen .config file. It compiled and 
installed fine. I'll reboot, and if I have any problems, I will do a follow up 
post.
