Comment 7 for bug 256817

Hi Jaime,

You may try building tp_smapi from source. It requires installing linux-source, unpacking the tarball at /usr/src and then making a symlink to /lib/modules/$(uname -r)/source

More detailed instructions here:
http://www.thinkwiki.org/wiki/Tp_smapi#Installation_on_older_Ubuntu.2FDebian

Link to the latest tp_smapi:
http://sourceforge.net/project/showfiles.php?group_id=1212

You should be more lucky than I am, since tp_smapi currently doesn't work on Centrino 2 thinkpads (x200s, T400 and T500 confirmed)
