Please do not confuse the usage of  a  ramdisk  image  with  standard
distributions  like RedHat etc. With Embedded Systems a ramdisk image
usually severs a bit a different purpose.

valid kernel boot argument.

Yes, "root=/dev/ram" (or usually "root=/dev/ram rw") is  the  correct
kernel boot argument for booting with an initial ramdisk image.
