The "root=" option tells the kernel what device to use for the root
filesystem. It is only used if you do _not_ use an initial ram disk
(initrd). If you use initrd, it is up to the script in the initrd
environment to determine the root filesystem and tell the kernel what
device is the real root via /proc/real-root-dev. The initrd script
normally looks at the kernel command line to determine this device, so
it could be "root=", "real_root=", "my_root=", "blah_blah=", etc. It
just depends on what you used to create the initrd that determines what
the script looks for.
If you create a directory "/initrd", your initrd should be mounted there
when you next reboot. You can then take a look at the /initrd/linuxrc
script if you want to understand more.
You can also mount it manually by doing:
gunzip < /boot/initrdXXXXX >/dev/ram0
mkdir /initrd
mount /dev/ram0 /initrd
