Why not. :P

Anyway, calling the old ioctl code if the new one fails, should be
compatible enough. (and the new structure contains the old one, so no
need of having 2 variables).

It would be even better if somebody finds out what the error for not
supported function is (I don't feel like checking 16000 error codes),
but it is not critical.
