I've rebuilt and am happy to say that nothing is hosed and I booted successfully :) Here's my sysctl output: $ sysctl hw.acpi.cpu hw.acpi.cpu.max_speed: 8 hw.acpi.cpu.current_speed: 4 hw.acpi.cpu.performance_speed: 8 hw.acpi.cpu.economy_speed: 4 hw.acpi.cpu.cx_supported: C1/1 C2/1 C3/85 C3/185 hw.acpi.cpu.cx_lowest: 0 hw.acpi.cpu.cx_history: 23589/0 0/0 0/0 0/0 I played with the different levels a bit, and can't tell much difference in them. Let me know what else I can try to break with this. Just for the info, I booted with a/c plugged in, but did the sysctl running on battery. Thanks Nate for the hints..
