Damn, thats going to make my life complicated.
What if I designate a section, that is beyond the 64K boundary, will the 
compiler handle it when I address data within that module?
Or I guess my question should be; other than the Atmel example code, how 
do others handle this issue?

The Atmel example code, using the far_mem_write/far_mem_read functions 
slow my memory accesses down to 1970's speed.
