As Matt says, there's only two SDM lenses currently available; the two DA* zooms. Beyond that, rumours / hints from "people in the know" have more lenses being announced in January; presumably at least some of these will include SDM since it's supported by both the K10d and K100D Super.
As for the third-parties there's even less information; they may be working on reverse-engineering in order to make SDM-compatible lenses, or they may simply be waiting to see what happens to post-takeover Pentax before going ahead. Either way we'll be the last to hear about it.
