Should it blogged about it last night!  ScottGu has a great post on the new CSS Control Adapter Toolkit for ASP.NET 2.0.  This control adapter gives CSS-friendly capabilities to pre-excisting ASP.NET controls (Menu, TreeView, DetailsView, FormView and DataList).

Pretty nice way to hook into the new Control Adapter Architecture for ASP.NET 2.0.

Check it out if you got the time.
