Hi Sami,
the doc you refer to is rather old, so while it is true that Cisco did provide these files at that time, in the meantime these files were never updated.
So the latest available is the one you can find here:
http://www.cisco.com/cisco/software/release.html?mdfid=281191384&release=8.0.3&relind=AVAILABLE&flowid=4378&softwareid=280775065&reltype=all&sortparam=
(for french, get translation-kit-8.0.3-fr.zip )
To be honest I don't know how much these files have changed in the meantime - you can give them a try and see.
If you want you can then merge this old .po file with the latest template (using a tool like http://poedit.net) and then translate the newer messages yourself (and possibly post the result here for other people to use ).
hth
