gkrellm only shows temp from one gpu

Hi all,

I am running gkrellm 2.3.5 and Ubuntu 11.04.
I have two GTX 460 cards in my machine which are recognized properly when I launch nvidia-settings, however with gkrellm (as well as gnome sensor-applet) only one of the cards is recognized. How can I get the temperature to show up for both cards?

below is the output from nvidia-smi -q -a:
