You can see which files are opened by a program with:
	strace -f -e open <program>

I would assume that unless specifically requested, SDL will use first one 
(which would be fb0).

Same as with PyGame.  Just set suitable SDL environment variables.
You can do it e.g. like this:
	var1=value var2=value ./hatari <options>
