Right, the problem likely is that /proc/diskstats in newer kernels also
provide proper stats for partitions, which it doesn't do on older kernels:

[dag@rhun ~]$ cat /proc/diskstats | grep sda
    8 0 sda 196482 22091 3600800 1524365 304150 614172 7355412 45110870 0 1321463 46646670
    8 1 sda1 1033 10862 2 4
    8 2 sda2 215888 3587367 919426 7355408
    8 3 sda3 1199 1411 0 0
    8 4 sda4 427 872 0 0

If you look at the plugin you will see what I mean.
