Thanks to the Speedstep extension by prasys and 8.9.1 kernel, S3 sleep, PSU, CPU fans, HD powered down, is now working on my hackintosh. It is also waking up properly with one exception. USB devices are not working when the hackintosh wakes. They need to be unplugged & replugged into the PC. Once that is done, they seem to work well. Has anyone managed to solve this problem?

My hackintosh is C2D 6600, 945P m/b & 7900GS (natit dual 0.2).

prasys? any ideas?
