..'lshw -v' says?  Should help yield googling ideas, e.g. chipset names.

..it _also_ which exact distro you run, and under at least Debian,
there are _several_ good ways to do this, which is why you need to 
tell us or your distro user group, what exactly you're running.
If you dunno, you probably went with your distro installer's defaults
and will need to tell your helper that, so they can help you figure 
out what you're running and what you should run and how to set that 
up.

..duh!  Ok, the above remains useful for all distros.
You Thorsten and other Fedora users wanna chk:

..noted.  My _guess_ is some new fan control chip needs a newer or
different kernel module loaded, and you should be able to set up that
easily re-running the setup program.
