I had that with 2.1 - you're not alone.
You might consider this option:
It's not 2.2 per se.
It's that these apps can send something that I think I remember is called an INTENT and that wakes another.
The problem with the crapware is that it tends to cascade once it gets started.
I can't guarantee that the suggestion above will help but you might want to consider it.
The only other real recourse is to wait for them to find a root method for 2.2 and then when you get the chance, root your phone and tear out the stuff that's making your life hard.
That is exactly what I ended up doing, despite wanting to be "just a regular user."
Anyway, welcome to the forum!
