Munir is of course refering to the hard drive space used by all binaries
of a single kernel:

/boot/vmlinuz[-version]	    .5-1.5MB compressed 1-3MB uncompressed    
/boot/initrd[-version]      .5+MB compressed    4+MB uncompressed
/lib/modules/<version>/*                        0-50+MB uncompressed

These object files can be stripped for an about 10% space savings.

Actual space used by the kernel in memory is 1-3MB for the kernel plus
4+MB for the initrd which is released after mounting the root filesystem
during boot up.  Plus any modules that are loaded and any kernel
structure memory allocations.  This adds up to only a few megabytes,
excluding the fact that the kernel uses almost all remaining memory for
expendable buffers.
