It seems the problem is, that LGPLv3 imposes additional restrictions not found in the GPLv2. So it isn't the LGPLv3 that forbids LGPLv3 libraries to be used by GPLv2-only programs. It is the GPLv2 which forbids to linking against libraries more restrictive than itself. See http://www.fsf.org/licensing/licenses/gpl-faq.html#v2v3Compatibility for details. In theory LGPLv3 allows addition of exceptions, but they have to be approved by all copyright holders. Doubt this will happen. So only chance for upgrading to a new version of the LGPL is waiting for an FSF approved version of the LGPL, which drops those additional restrictions for GPLv2-only programs. Total insanity...
