The lads from Nuoro have published topos to some of their favourite up-to-now-not-documented spots, see http://www.bloccobirra.com/contones.html . From each area, there's a pdf you can download. Angelo is progressively writing a guide to bouldering in the island, at least all except the southern bit.
For Serra Oseli, the place I go, there is the latest update at http://www.peteranne.it/docs/Serra_Oseli_sett2010.pdf
