What is the value of the hw.acpi.cpu_cx_lowest sysctl node? If it's 
different from C1, try to force it to C1. If it fixes your problem, 
could you make available somewhere a verbose dmesg boot, the asl of you 
system (see acpidump(8)) and the output of "sysctl hw.acpi" and "sysctl 
dev.cpu" so I can have a look at it?
