That's not a kernel problem but how module parameters are passed to
modules loaded from initrd and is distro specific.  Please note that
kernel will spit the message even when the module parameter is later
picked up by initrd.  So, please ping MDV for instructions on how to
pass kernel parameter via initrd.
