The "telecoms package" is a legislative proposal that creates a government body that can ban copyright violators people from Internet access without any judicial process. Sarkozy's government is the main advocate of this.
Luckily, the European Parliament rejected the proposal - they amended it to say almost the opposite, confirming people's right to a judicial procedure.
The European Commission have said they accept the Parliament's amendments, but it's sometimes hard to trust the European Commission. The next stage of the legislative proposal is a vote by representatives of the national governments (the European Council). To block Sarkozy's proposal, letters should be sent to the relevent minister in our national governments.
I put this info and some links to the relevent documents here: http://fsfe.org/en/fellows/ciaran/ciaran_s_free_software_notes/eu_states_to_...
