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).

I believe it was more fully documented in the later pre-2.0 kernel packages.
