Hi!

I was always a bit reluctant to apply the kernel patch... but now it works=
=20
out of the box. I used experimental versions of hdapsd and tp-smapi. It=20
might work with the ones in Lenny too, but I did not test it.

YAY! ;-)

Maybe it helps someone who was reluctant about the patch too ;-) - whether=
=20
with or without good reason, I did never take the time to actually look=20
at the possibly completely harmless patch.

Ciao,
