Sadly the OpenCL stuff uses a manual blacklist that has to be maintained by
the user. I don't like that solution as at least 99% of the user don't
understand how to handle that. For OpenCL we also have the option of
running a short test whenever the driver/device changes. That was my
original idea for the OpenCL blacklist when it was discussed.

Of course we should make sure that if we want we can use the same mechanism
for other features as well.
