Now I suddenly have dev.ichss :) :
dev.ichss.0.%desc: SpeedStep ICH
dev.ichss.0.%driver: ichss
dev.ichss.0.%parent: cpu0
dev.ichss.0.freq_settings: 794/-1 496/-1

dev.cpu changed also a bit but most importatnt: The error has gone and I 
see the CPU changing frequency :)

ev.cpu.0.%desc: ACPI CPU
dev.cpu.0.%driver: cpu
dev.cpu.0.%location: handle=\_PR_.CPU0
dev.cpu.0.%pnpinfo: _HID=none _UID=0
dev.cpu.0.%parent: acpi0
dev.cpu.0.freq: 62
dev.cpu.0.freq_levels: 794/-1 694/-1 595/-1 496/-1 434/-1 372/-1 310/-1 
248/-1 186/-1 124/-1 62/-1

Some questions left: Does cpufreq check for different drivers and attach 
the next best which seems to fit?
Does the acpi_perf/ichss driver also adjust the core voltage according to 
the frequency?

Thanks a lot, now I need someone to help me with my S3 suspend death ;)
