I disabled bluetooth with:

hciconfig hci0 down

But the noise still happens as before. Any clue? Is there other modules I
have to unload?
I really want to know what the root of this issue is, mostly due to the fact
that 2.6.18 doesn't have the issue...
I know disabling C3/C4 stops it, but that isn't the root of it as
2.6.18goes into those states fine without the issue popping up.

P.S. How does one go about getting involved in Ubuntu development,
especially with regards to laptop and core system issues like (but not
necessarily identical to) this one? I've run into many issues along the way
and would like to help somewhat beyond simply reporting them
