No, the current API would not support this.

These kind of features are a subset of general hardware support (rather
than simple arch specific extensions like the s390 stuff), which I think
we need to take into account before making changes to the API.

Perhaps we should set up a list specifically to discuss & implement the
hardware crypto API, as there seem to be several disparate efforts going
