I doubt that this could be done in less than 100 bytes. A descriptive error 
message string alone will probably be around >= 60 chars. But I know this is 
nitpicking.

I'm still voting for adding this 2k and doing it correctly on all boards. With 
the option to disable this 64bit support (as Scott suggested) on boards with 
very tight resources.

Best regards,
Stefan
