[SOLVED] get kernel command line parameters in bash

Let's say that when booting I edit the kernel line in grub boot screen and pass my_special_parameter at the end like:
kernel /vmlinuz26 root=/dev/md0 ro vga=773 my_special_parameter

I'll edit /etc/rc.sysinit and do some mounting IF my_special_parameter is present in kernel's boot line. So I'll have an:
if [[ my_special_parameter is there ]]; then ... fi
or something like that.

So how can i write that condition? is kernel's boot line stored somewhere, in a variable, file, /proc value? It has to be somewhere...
Thanks!

P.S. I'm not sure if I this is the right place for this subject. If not, please move it where it belongs.
