slowly varying inputs

I'm trying to use the slowly-varying inputs comedi functions with my
NI-PCI6071e (comedilib-0.7.22, comedi-0.7.70, linux-2.6.12). 

The "sv" demo program reports an error "comedi_sv_measure():
Inappropriate ioctl for device". In all other respects, my IO-card seems
to be functioning fine (streaming AI, AO and digital input all seem
fine).

I see in the docs, the comedi_sv_* functions are listed as depreciated.
Does this mean they're known to be broken, or do I have a problem with
my card. What's the easiest way to implement this functionality, if
these functions are indeed broken?

thanks,

Bryan
