I was using gcc-3.2 -S -O2 which for my build defaults to --march=i386. Indeed, using --march=i486 produces the same output as gcc-3.3/gcc-3.4. In fact, using --march=i386 on gcc-3.3/gcc-3.4 also removes the duplicate reloading. So it seems that it's really a difference between --march=i386 versus --march=i486.
