Did you actually do a clean build after installing sdl-devel? You need to 
either delete your build directory or do "make clean" before rebuilding. 
Otherwise qemu will reuse the old (output disabled) object files.

That's normal. When the guest suspends the CPU (via the HLT instruction) 
there's no need to qemu to do anything, so it doesn't. Real CPUs do the same
