Would it be possible to know when backend drivers
will come into xen/next-2.6.37 ?

No, mainline won't get any device backends until .38 at the earliest -
.37 is closed for anything except bugfixes.  But I'll maintain a .37
based tree with all the extra bits in it for full use.

However, with block backends specifically, we're considering doing away
with a kernel-based backend altogether and deferring it to a usermode
process, so that will be independent of the kernel.
