Rubbish.  The kernel's requirements are well documented, and have been for
years.  The reason we've documented it is because it _matters_, and it's
hard to sort out this crap before the kernel starts.

Think about it - think about how many different L2 caches there are out
there.

Think about how difficult it is to locate the L2 cache controller when
you don't know what platform you're running on.

Think about how difficult it is to disable the L2 cache.

Think about how difficult it is to flush the L2 cache, when you don't
know what sort it is, where it's located, or what instructions to use
to do that.

The kernel cares about its boot environment beacuse of these issues.
