That is my opinion too.
The Debian packager could exploit clause 4b (see
http://creativecommons.org/licenses/by-sa/2.0/legalcode) by modifying
the OSM data and distribute them (as Derivative Works) under the terms
of CC-by-sa-v3.0.

But my opinion is that CC-by-sa-v3.0 also fails to meet the DFSG.
See
http://lists.debian.org/debian-legal/2007/03/msg00105.html
http://lists.debian.org/debian-legal/2007/09/msg00176.html

On the other hand, other people (including the FTP masters) seem to
disagree with me and think that CC-by-sa-v3.0 meets the DFSG...  :-(

Agreed.

My suggestion is: try and persuade upstream to change licensing policy
(I admit it's a hard task, especially because I have the impression
that the copyright holders are numerous...) and have the data
re-licensed in a DFSG-free manner (e.g.: under the terms of GNU GPL v2).
