Mattia,
Ok, it would help if I sent a patch against the right kernel (2.6.30-rc3).

Subject: [PATCH v2] UBUNTU: Sony laptop: Sony Vaio laptops do not enable wwan power by default.
Bug: https://bugs.launchpad.net/bugs/364678
Added quirk to enable wwan power based on DMI information already present in the module.
It appears that Vaio's do not enable power to wwan from a cold boot.
