Hi,  for your second problem there is a little workaround: the linker 
uses the 'avr85xx.x'- linkerscript. This
did not work for me either. Copy the 'avr2.x'-likerscript to your 
project-directory and change it to fit your needs (sram size etc., 
without xternal ram, it should work without changes !).

Call the linker with 'Wl,--script,$(PROJECTDIR)avr2.x,-Map,$(TARGET).map'.
This works for me.
No more overlapping sections.
I use gcc 3.3.1, binutils 2.14 and avr-libc 1.0 .

greetings !!!
