I just hacked together a bunch of GKrellM plugins to display data gathered from the ibm-acpi driver. Data displayed is CPU, GPU, HDD, Mini-PCI, Battery temperature and the fan speed. Every value has it's own plugin, the display is very simple with no config. options.
Download it here: gkibm-acpi-0.1.tar.gz
Many thanks to Brad Davis for gkfreq, my code is totaly based on his plugin!
