Hi I upgraded to the full licensed driver but unfortunately it didn't fix the problem, so I guess it isn't a modulation issue. However, one last thing I was wondering, although it's not possible to run the driver in debug mode, how about the kernel? I did notice that there is a "linux-image-debug" package for ubuntu. Would running the kernel in debug mode provide any useful information? I just have a gut feeling its something to do with how my amd64 system is set up rather than anything else...
