Yes, that's what I use.  The OP mentioned AVR Studio and I assumed 
(probably incorrectly) that he was using avr-gcc and avr-gas.  All of 
my comments were based on that assumption.

With regard to multiplying by two to get a word address, this is only 
needed if you are going to use the address to refer to code.  For 
example, if you want to use the ijmp or icall instructions you must 
have a word address in r31:30.  For use with LPM, you want a byte 
address in r31:30.
