It should work with the patches I have provided. It seems not to be
so much work, maybe I should prepare a new release included.

Would you consider adding .overlap

http://support.atmel.no/knowledgebase/avrstudiohelp/mergedProjects/AVRASM/Html/directives.html#OVERLAP/NOOVERLAP

to places where the code generated overlaps:

in drivers/usart-isr-tx.asm:

.org UDREaddr
   jmp_ usart_udre_isr

in drivers/usart-isr-rx.asm:

.org URXCaddr
   jmp_ usart_rx_isr

Alternatively, we can use .ifdef to skip original interrupt handlers
where necessary.
