What I meant was... Creative's drivers might not be vista-ready yet. It's not because of asio or wdm compatibility; Sonar can work with either driver model, plus Sonar 6 works quite well with Vista, ASSUMING you can download the 6.2.1 vista update from Cakewalk's site (and I've seen the other so-called 'updates'). Asio4all works with XP quite well but it is somewhat flaky under vista since the 2.8 release is still beta and it only supports 32-bit vista, not 64-bit.
