The config option will probably be removed at some point. It's just
there to aid debugging in case someone reported block dev problems.

In the *unstable* series you really shouldn't be relying on
compatibility between different versions of the tools, xen, or the
kernels. You should always install a complete set of binaries. In the
unstable series we reserve the right to change interfaces, and
frequently do. 

Best,
Ian
