that comment is true for old style drivers, but looking at other drivers they also only skip this for NET_MPSAFE kernel builds. Nick, do we need to make these go back to non-mpsafe stuff for networking if !NET_MPSAFE? eg, look what wm(4) idoes with WM_MPSAFE usage. are we getting ahead of ourselves in usb? :) .mrg.
