And yet again, if you have a kernel with a built-in console= setting,
there is _no_ _way_ to disable that console via the kernel command
line.

So what if some of your platforms need one console, others need a different
console, but must not use the first one...

Do we need nomem= and noconsole= options too?  Or do we just do the
sane thing and get rid of CMDLINE_EXTEND - or insist that stuff like
console= and mem= options are never built-in ?
