In Lion look for AICPMVers instead of CSTInfo.
PerformanceStateArray should be there.
Type "Wait=yes -v" at boot or run "bdmesg" in terminal, you should see
SSDT with CPU C-States generated successfully
SSDT with CPU P-States generated successfully
I've tried to remake a DSDT and it seems that it has values on AICPMVers & PerformanceStateArray, but still nothing on CSTInfo. Does it mean that my speedstep is on now?
