http://www.insanelywind.com/forum/viewtopic.php?f=41&t=2733I am currently running SL 10.6.0
I used
this voodooPowerMini v1.2.4 into the EFI partition and everything worked smoothly.
source. Just to let you know, I am using NullCPUPowerManagement.kext and Disabler.kext to accompany voodooPowerMini.
But when I installed voodooPowerMini 1.2.7 into the EFI partition and I got a kernel panic.

I used the debug version of voodooPowerMini but not really sure how to extract the kerenl panic info.
