ksysguard don't detect all temp sensors

Hey all
ksysguard don’t detect all cpu temperature sensors. I’ve got an ASUS k8n-DRE with 2 dual-core Opterons. ksysguard can see core 0’s and core 1’s temp but not the second cpu’s. ‘sensors’-command result in

sensors

k8temp-pci-00c3
Adapter: PCI adapter
Core0 Temp: +46.0°C
Core0 Temp: +36.0°C

k8temp-pci-00cb
Adapter: PCI adapter
Core0 Temp: +44.0°C
Core0 Temp: +40.0°C

Is there a way to let ksysguard know that there are more than two?
