I don't think it's that simple. While said developers keep saying this, 
they also say, in the same breath, that only GPL-compatible licenses are 
acceptible. see http://lwn.net/2001/1025/a/module-license.php3 for one 
example. Or the following excerpt from insmod(8) from modutils 2.4.12 for 
another:

The IBM public license is not GPL compatible. There is a miniscule chance 
that the forthcoming new GPL will have language about patent licenses in it 
which will make the IBM public license compatible in that respect, but even 
if it does, it's been claimed that licenses that refer to specific legal 
jurisdictions  are not GPL compatible. (see
