autoboot_delay=NO is documented to wait for input and *not* autoboot, which is the exact opposite of the current behavior. Additionally, autoboot_delay=-1 is documented to disallow the user from interrupting the boot (i.e. autoboot immediately), which was not previously honored. This also fixes the case insensitive comparison to be truly case insensitive. This is kind of nit-picky, but the previous version would only accept "no" and "NO".
