Yes, it is a module and yes I did a reboot. I can remember having specified minstrel when compiling the kernel instead of pid so perhaps I need to reconfigure/recompile the kernel?

I think it is possible to pass parameters to built-in's, but it has to be at the boot parameter stage... not sure about the syntax for that, but it is possible. --- On Sat, 13/2/10, Ernst J.
