Indeed. And additionally I somehow assumed .rodata would be tiny comapred
to .text - but looking at sizes in actual kernels I see it is really huge
(big enough to benefit from 1Mb pages on amd64; not quite big enough
for 4Mb pages on sparc64).

I wonder how much of that is driver specific firmware that is never going
to be needed on my machine - I should use more modular kernels maybe.
