Hi Sebastian, Armijn and others,
I can only follow what Armijn has been writing.

While the ideas and thoughts regarding the legal implications of EXPORT_SYMBOL_GPL are wide (see e.g. http://lwn.net/Articles/154602/) and there is no precedent as far as I know, there seems general consensus that it _at least_ signifies the explicit intent of the author.
By using the _GPL variant, the author unmistakingly indicates: "I consider any use of that symbol to create a derivative work which must again be licensed under GNU GPL"
So by modifying a _GPL symbol into the non-GPL variant (and using the code from a non-GPL module), one would clearly violate the intent of the original author. Whether or not that intent of the author is grounded in copyright law may depend on the specific jurisdiction, circumstances and the judge that would make up his mind about it, if such a case ever went to court.
I would be interested to hear what DaveM, James Morris and Herbert Xu as the authors of the files in question have to say about such activity.
