In an attempt to answer my own question, I came accross:
Blowing by the strongly worded "at your own risk" disclaimer on the top of
the page, I forge onward to "Reasons for NOT compiling a custom kernel":
"You merely need to compile a special driver. For this, you only need to
install the linux-headers packages."
Could this be the case? Is ivtv "a special driver" or not?
"You have no idea what you are doing, and if you break something, you'll
need help fixing it. If you hose your box, reinstall. Don't bother asking
Now this one seems dead on. Given my track record, I would put chances of
"hosing my box" somewhere upwards of 99%. :)
