Frans,

can't say about the 280R, but the fan control on the Blade 1000/2000
worked until kernel 2.6.29, when it stopped working and hasn't worked
since then. If you downgrade to a 2.6.28 kernel for example, you don't
need any tool for it to work, you just need the CONFIG_ENVCTRL option
enabled in your kernel either as built-in or as a module.

@all: feel free to correct me if i'm wrong :)
