On my 1.5.3_ALPHA kernel, the kernel itself takes up nearly 4MB (look at
the "dec" (for decimal) column):

	thoreau:~ 1172> size /netbsd 
	text    data    bss     dec     hex     filename
	3292972 260552  380744  3934268 3c083c  /netbsd

The other ``missing'' 4MB would be various other miscellaneous data
structures set up at kernel boot time.  One reason that the buffers
might be reported separately is that they are usually the largest of
these data structures.
