As the number of features has increased, kernels have gotten somewhat
larger. There was a limit on the size of the compressed kernel with
zImage (I don't know what the limit was), and bzImage has a larger limit,
like 1 MB compressed (~2 MB uncompressed). This started in 1.3.73.

Bits and pieces in /usr/src/linux/Documentation/Changes and the LILO and
LOADLIN documentation. I believe it was more fully documented in the
later pre-2.0 kernel packages.
