Nope, the wiki page is correct. Both the vanilla kernel and the rt-preempt kernel use the "uspace" flavor of linuxcnc. The uspace flavor runs entirely in userspace, which is where it gets its name. If you run the uspace flavor of linuxcnc on an rt-preempt kernel, you get reasonable realtime performance. In userspace! Awesome! If you run the uspace flavor of linuxcnc on a vanilla (non-rt-preempt) kernel, you get crappy realtime performance, and it behaves like the old "simulator" flavor. And by the way, there's a new & better place for the "Updating to 2.7" documentation, here: http://linuxcnc.org/docs/2.7/html/getting-started See specifically the "Getting LinuxCNC" and "Updating LinuxCNC" sections. I'll update the wiki to point there, hold on...
