Yes, right now I'm using my theme layer with the css included; I have the Use layout's stylesheet checked and I have no extra css in the Customize css box.

Sure: the layout (a port of a WordPress theme Motion) was originally posted at dreamwidthlayouts, and the original css can be found at penemue's journal. A screencap of the layout is here. I had asked about the layout there as well. branchandroot suggested that this should be converted to one of the official DW themes.

Hope this helps!
