I totally agree with this.

One solution could be, for example, to use ViennaCL
(http://viennacl.sourceforge.net/). There is distributed under MIT
license, that is compatible with the GPL. It contains an
implementation if BLAS and some matrix decompositions in OpenCL. But
it has a problem (or I think it is a problem): is possible to use
OpenCL code without using non-free software? About the library
implementation, exists pocl (http://pocl.sourceforge.net/), but AFAIK
only produces code for CPUs. An the last problem is: is possible to
run code in a GPU without the privative drivers?

With the Open AMD Driver, yes/soon :D
