With a custom kerel, that should still be possible.
For a v3.12-rc6 mac_defconfig kernel, the figures are:
-rwxr-xr-x 1 geert geert 4873408 okt 20 11:31 /tmp/vmlinux*
-rwxr-xr-x 1 geert geert 2333743 okt 20 11:31 /tmp/vmlinux.gz*
-rwxr-xr-x 1 geert geert 2190667 okt 20 11:31 /tmp/vmlinux.bz2*
-rwxr-xr-x 1 geert geert 1802956 okt 20 11:31 /tmp/vmlinux.xz*
With some stripping, you should be able to fit (at least the xz version of)
the kernel on a floppy again.

I know.
I even booted Linux with X and twm on an Amiga with 2 MiB chip RAM and
2 MiB Fast RAM (+ swap, of course). The uncompressed kernel fit
easily in 2 MiB.
