In general, a 2.6 kernel will be bigger than a 2.4 kernel with a similar
config. That's been the case with about every major kernel upgrade. I've
still got some 2.0 kernels someplace that are much smaller. Also, ppc
code is on average bigger than x86 code. It's just a property of the
instruction set. The x86 uses variable sized opcodes, so some stuff is
only one or two bytes. The ppc instruction set uses exactly 4 bytes
for everything.
