A few emails ago you were worried about wasted cycles.

boost::hash should work well with std::unordered_map as it's defined
in the standard and boost::unordered_map should work well with
std::hash as it's defined in the standard. If that isn't the case then
they're failures. These are generic components, they should just work
without a wrapper or any such fuss.
