I think I might know what it is, check out these threads to see if they're describing the same noise/vibration that you're feeling.

Apparently the ABS system does a self check or something of the sort after every startup, once the wheels are moving. I've never really noticed it in my MY04, but those threads seem to be describing exactly what you're feeling/hearing. Hope this helps!
