You can trace IO register address reads with:
	--trace io_read

But it may provide so much output that you'll want to redirect it
to a file so that you can grep for that register afterwards:
	--trace-file somefile.txt

However, the problem is that rest of the code (starting from TOS,
at bootup) is fairly likely also to access that register, so you
need to somehow differentiate them...
