GPLizing BSD licensed sources

[Yaroslav Halchenko <debian@onerussian.com>]

Dear Legal people,

I am looking for a quick hint. lush project ships sources of modified
version of libsvm which is released under BSD license. Since lush is
GPLed, and they heavily modified those libsvm sources, they added a
generic copyright + GPL excerpt on top above original BSD license.
Please see
http://pastebin.com/d7d42ea06
for an example.

Although no clause of BSD license seems to be violated, I still have
some unpleasant aftertaste. Am I right that technically it is ok?

or may be file needs cleaner header which would state explicitly that
only modifications  since original version LIBSVM-2.5 are under
GPL and copyrighted by lush authors?

Thanks in advance for the clarifications
