That probably means your simulator doesn't properly includes the ROM
part that carries the .data initialization values.  This also used to
be a problem with AVR Studio, but has been fixed in their recent
versions (AVR Studio 4.08+ together with the coff-ext-avr file
format).

Perhaps you could tell your simulator to initialize the ROM contents
from a hex or binary file, and only use the COFF file for obtaining
the debugging symbols?  That way, no special precautions are required
on the simulator side.  (VMLAB works that way.)
