Yes.  It will be a little more work.  The cx25840 module needs some
cleanup which I've had the best intentions of actually doing for some
time now (but haven't :( ).  Also the ivtv driver can support different
diigtizers than the CX2584x, so the control handling for when one has a
CX2584x, or not, might be more complex.

Hans was supposed to be reworking general v4l2 control logic this
weekend.  I need to ask him about a number of things: adding a
"technician" controls class, supporting mutliple sets of audio controls,
doing menu controls across the main driver/v4l2_subdevice driver
boundary, and generally making controls easier to implement.  (They are
a little tedious - maybe that's because I've never needed to make them
before.)

In short, I can add them, but I'm pretty sure it's not going to happen
soon.  I have travel this month and in September, and an IR controller
implementation I want to get done first:
