Hah, you really had me second guessing myself about it too. But I just re-installed SS 4.5 over top of itself (without wiping anything except cache which I do all the time to keep things speedy) and the notification text is back to white on black. Everything that gives notifications is white; meebo, screenmode widget, e-mail in Gmail and k-9, GTalk. So this further leads me to believe this is an Android OS file/setting because I don't think Chevy would have modified screenmode widget notifications since it's a more obscure app. But again, you would know more than me, heh.
