Ubuntu :: Silence On Screen Console Messages At Bootup?

After grub loads the kernel I'll get an on screen message from the console showing: cannot reserve MMIO region And I was wondering is there a way to silence console messages so you don't see them at bootup?

Could setting dmesg work:-nlevel Set the level at which logging of messages is done to the console. For example, -n 1 prevents all messages, expect panic messages, from appearing on the console.So typing at a term 'dmesg -n 1' will work?
