How to display kernel command line parameters?

view story

http://unix.stackexchange.com – In the grub.conf configuration file I can specify command line parameters that the kernel will use, i.e.: kernel /boot/kernel-3-2-1-gentoo root=/dev/sda1 vga=791 After booting a given kernel, is there a way to display the command line parameters that were passed to the kernel in the first place? I've found sysctl, sysctl --all but sysctl shows up all possible kernel parameters. (HowTos)
