I have also q6600 and no problems with acpi turned off- all 4 cores show up normally. Maybe you miss CONFIG_MCORE2=y or some other setting in kernel config? Quoting "J.Miribel" : Same here. acpi=off as kernel param and I'll have only one core showing up. You can use acpi=ht to turn acpi code on only for multi core functions, but I still get some FPS drops..
