Short summary:

I fetched the suse src rpm as mentioned in my first post. I extract
the files with alien -g rpmfile on my debian system. What i got was
the whole directory structure. I supplied manually only the xen
patches. At this time, i did not get any error while patching, so i
thought it works but it did not!

Even though i had no error messages during the patch process a make
menuconfig gave me the following:

drivers/xen/Kconfig:23:error: found recursive dependency:
XEN_UNPRIVILEGED_GUEST -> ACPI -> NUMA -> ARCH_SPARSEMEM_ENABLE
-> ARCH_SELECT_MEMORY_MODEL -> SELECT_MEMORY_MODEL -> DISCONTIGMEM ->
NEED_MULTIPLE_NODES -> XEN -> XEN_UNPRIVILEGED_GUEST

Any idea how to solve this easily? It seems that
XEN_UNPRIVILEGED_GUEST depends on XEN and XEN by it's own depends on
UNPRIVILEGED GUEST. That might be wrong specified in the Kconfig file
and get fixed by one of the suse patches. I have to admit that i did
not invest much time to work that out. Help is greatly appreciated.

To confirm that assumption, i applied all suse patches and xen boots
without problems at all.

Currently xen is up and running on my debian etch notebook with
2.6.25-16 kernel but with all patches included in the kernel tree.

Regards
