La Gazzetta dello Sport has provided additional information about Basso’s alleged links to Eufemiano Fuentes (thanks to zarathustra on the DP Forums for helping with the translation from Italian - any errors are mine, though).

In a conversation between Fuentes and Labarta, taped on the evening of May 14 - just hours after Basso’s stage victory on the Passo Lanciano - Fuentes and Labarta apparently discuss the result of the race, and Fuentes says in a mischevous tone”A strange rider won: Basso, Ivan Basso.” Labarta replies knowingly: “A certain Ivan Basso”.

According to La Gazzetta, Labarta later seems to be complementing Fuentes as he observes that Basso and another alleged client, José Enrique Gutierrez, occupy first and second place on general classification.

Labarta: “Good, my boy, a certain Basso and a certain Guti are first and second.”
Fuentes: “My goodness”.
Labarta: “You have first and second”.

After stage 7, they also discuss the rider Birillo.

Labarta calls Fuentes to talk about the results and outlines the great performance of the “Bufalo” who finished 4th.
Labarta then gives more informations to Fuentes about the results: “Savoldelli, yes, and then after 16 seconds arrived Birillo with Simoni, at 20 seconds Zapatero, at 24 seconds Uno. All very well. I want to say that all of those riders which are interesting for you (….) are in the race and have done well.”

[Zapatero > alleged to be Scarponi, Uno > alleged to be Unai Osa.]

The result of stage 7:
1 VERBRUGGHE Rik
2 SAVOLDELLI Paolo 0:14
3 MAZZANTI Luca 0:14
4 GUTIERREZ CATALUNA José E. 0:14
5 REBELLIN Davide 0:16
6 BASSO Ivan 0:16
7 HONCHAR Serhiy 0:16
8 SIMONI Gilberto 0:16
9 LEFEVRE Laurent 0:20
10 SCARPONI Michele 0:20

Only Rebellin, Honchar arrived with Basso and Simoni 16 seconds down. Somehow (not described in La Gazzetta) the investigator excluded that Rebellin and Honchar are implicated and came to the conclusion that only Basso can be Birillo.

Birillo also appears on another handwritten note taken from Fuentes and referring to testosterone patches, blood plasma, the female hormone treatment gonadotropine, and also the code for a Swiss bank account.

As always, it should be noted that these are reports from the press, and none of this information has yet been confirmed by the authorities.
