Background: I recently bought a HIFN crypto card and would like to use
it under Linux without the need to use some external patchsets :)

Not for now - either use acrypto [1] or ocf [2].

Yes, these two I meant with "external patchsets" :-)
It would be nice to have an asynchronous API in the mainstream kernel.
An the documentation says it is under development, therefore I ask :)

It is - Herbert's work on stackable algo registration is a first step,
although when we had async crypto discussion last time (about a year or couple
ago) we was unable to get into consensus - I still think that it is
quite impossible to have good async support with existing
software-oriented cryptoapi, while Herbert have some ideas in mind.

Work is being done, just not too fast.
You can find a brief todo in archive of how Herbert planned to implement
that and, if you like, get into that too - that would be very
appreciated.
