I think I found the part needed. It's an assembly with both the audio and cruise control buttons, and runs about $115 from Bernardi. I'm not sure what other parts might be needed.

Manual/AT Base(?): 36770-TK6-A31
AT w/ Paddles: 36770-TK6-A41

Exactly what I want to do as well. It seems like it really wouldn't be too difficult, Honda steering wheels practically seem like Lego's and with the wiring end not difficult (you have to buy an adapter to connect to an after market HU anyway) I think this would work quite well. Not the cheapest part though...

What bewilders me is why people are working so hard to add the controls to the stock unit Steering wheel controls won't help with the bad sound quality and awful file navigation For the same price as a multi CD player and USB adapter you could get a real HU with a decent DSP and quality D/A converters, and a multi-line display.

Anyway, for me getting the steering wheel button harness would be a double win because I have a Base model and plan on adding cruise in the near future (the Rostra kit should be out soon). Adapting the OEM buttons to the Rostra interface will probably take some work, but considering Rostra provides schematics for their controls I believe it could be done with some soldering and resistors. The complicated part is the ON/OFF button which I believe is a latch type on the OEM controls and a pulse type on the Rostra's. I could map the OEM Cancel button to it instead (Rostra doesn't use Cancel as far as I can tell), but it would be nice to have that button to use for something else...
