I appreciate the brevity of the site but it leaves a little to be desired. They should have a footer section that explains each option and what major versions of kernel support them, or at least a text link to the latest kernel command line arguments. [1]

Note the kernel version in the URL as the options evolve with time. Some will be deprecated and some added but the kernel does not always complain if you utilize a deprecated option or an option that does not exist.
