[linux-dvb] Hauppauge remote controls: old & new

I now have a Nova-T 909 to go with my Nova-T SAA7146. Using the stock
2.6.15.x cx88-dvb and related modules, it seems to be working well so far,
though the remote control repeat isn't right. (I recall something about some
fixes in this area; I'll give v4l-dvb HEAD a try tomorrow.)

(I've hit an aerial pass-through problem, significantly affecting at least
the multiplex containing the ITV channels; ISTR its being mentioned
previously on at least one of these lists. Cable-splitting works fine,

With the IR receiver[0] plugged into the new card, both remote controls can
be used but it is not possible to distinguish between them. (The old one is
model R808; the new one is model A415.)

With it plugged into the old card (and my patched budget-ci [1]), the new
remote control causes, for various keys, the following:

  budget-ci: received key NN address 1E

For reference, the old remote control uses address 0x1F.

Perhaps my budget-ci patch [1] should be applied and cx88-input.c should be
modified to use the address information to avoid remote control clashes? Or
should my ir-common patches [1] be applied and both drivers and ir-common be
modified to allow for large keymaps, making use of the RC5 address
information where available?

[0] I used the new one, but I doubt that that matters at all.

    The patches may not be applicable to current v4l-dvb HEAD; I'll check and
    update them (if needed) later.

Housework can kill you if done right.
