For LFS, they need an external program that uses Outgauge, I haven't found any, but I assure you there are some.

There's an experimental app that MadCatX is working on; the LEDs work, but you need to turn off FFB. Try it out here: http://www.lfsforum.net/showthread.php?t=68510

Keep an eye out for that thread; a version with FFB enabled might be out later.
