I agree.  I've played with booting kernels from kernels
in both PowerPC and MIPS in the past, and the problem
I always run into is drivers or kernel functions that assume
a particular power up state.  When rebooting from another
kernel you don't have the same state as from power up, and
some software doesn't like this.   I suspect main reason for
kexec is the horrible x86 bios and nothing that can be done
about it.

Oh, and I agree with your assessment, not that you are biased :-)
