If you' using a Debian-derived distribution like Ubuntu or Mint look for “linrunner” PPAs to get dedicated Thinkpad packages (HDAPS and others)
To have a gui to enable trackpoint press function and trackpad scroll, install configure-trackpoint from the repository mentioned above.
To enable fan speed control, install Thinkfan package ( It might require little edits on configuration files to work, and if you edit, be extra careful!)
If you are using a RPM-based distro like Fedora (I don't tested in SuSe, by the way), you can install tp_smapi to control the battery charging thresholds and control the APS module. For it compile, you need to install some packages, as described here.

Always remember that Thinkpads have a dedicated linux documentation site, thinkwiki.org, and because of a good native support a great number of linux users ( especially T and X series ), so if you' re in trouble with something don't give up and search for a solution on the web.
