Right, thanks for the hint! Some interesting data:
1) It is indeed PowerBook6,5 model
2) Fan data (it was adt*):
Node 0xff963c08: fan
name:
66 61 6e 00
'fan'
device_type:
61 64 74 37 34 36 37 00
'adt7467'
compatible:
61 64 74 37 34 36 37 00
'adt7467'
...
Node 0xff964910: fan1
name:
66 61 6e 31 00
'fan1'

Again, seems you're correct:
dev.cpu.0.%desc: Open Firmware CPU
dev.cpu.0.%driver: cpu
dev.cpu.0.%pnpinfo: name=PowerPC,G4
dev.cpu.0.%parent: cpulist0
dev.cpu.0.freq: 533
dev.cpu.0.freq_levels: 1066/-1 533/-1
