Now bootparams and any other stuff is prepared by kernel. So like a bootloader we just need to know 3 things. Kernel, initrd and command line and kernel should do the rest. In future we can define few flags to alter the loading behavior. Like force 32bit or 16bit entry instead of default 64bit for bzImage.
