guys you are not going to believe this, i am using appleintelcpupower management - no nullcpu kext at all so far in bios i have only enabled speedstep, not sure if its working or not as not quite sure how to check ioreg and extensions

on boot up it did say something about c states but was too quick to read in verbose mode

if someone can chime in and let me know how to check - also one more thing i changed my hpet slightly in DSDT as i compared to xxxslayeriixx and noticed few differences will try with old dsdt see if that is the case post back soon
