Yes, as Xen doesn't support non-PAE anymore.  Also note that the kernel

from the now-used ones -- they were from 2009-04-21.  Also, the Xen
version is still the same.

But why did it work until now?

Unfortunately not.  I rebooted blubber with a kernel containing this
patch; see the attached log file.
