It may still be impossible at the moment actually.  The
SNDCTL_DSP_MAPINBUF and SNDCTL_DSP_MAPOUTBUF ioctls are precisely
examples: they pass a struct which contains the address of a buffer.
This can not be expressed with the current handling of ioctls in
GNU/Hurd: the sound server can't read/write the client process memory.
