In a noon patched kernel the only parameter you need are
linux initrd=initrd.gz root=/dev/ram1 init=/linuxrc (see my 2.4.14
distro)
root=/dev/ram1 will load initrd fs in /dev/ram1. But after that you can
do whatever you want. In by 2.4.14 version of LEAF (see previous post)
initrd is loaded in /dev/ram0 and after that everything is moved over
tmpfs which is much nicer. But you have to be under 2.4.x :-)

initrd MUST be either ext2 or minix. Can't be tmfs :-(
