It appears that you're correct!  I was lead down the primrose path by 
someone who assumed it was a device which provided read access to the 
analog output setting.  My cover is blown -- it's now official that 
everyone knows definitively that I know little to nothing about what I'm 
doing.  :)

I don't know how beneficial it will be, but I have nearly completed a 
driver for the DAC5571.  We're currently using Linux 2.4 in our embedded 
project, but we may soon be upgrading to a 2.6 kernel.

We're using the tqm8260Algorithm-bit adapter.  Are you familiar with it?
