After kexec-tools compiled, I actually tried it:

# kexec -l /boot/2.6/zImage --command-line="root=/dev/hda6 ro"
# echo $?
# kexec -e
Starting new kernel

....but then the system just hung there, no more messages, I had to
powercycle it.

The --debug options is listed for "dol-ppc" systems (I have a PowerBook
G4, not sure if this falls into this category), when I use it the help
screen of kexec is displayed again and at the bottom:

   Cannot load /boot/2.6/zImage

This is with 2.6.34-rc7 (today's git):

# file /boot/2.6/zImage
/boot/2.6/zImage: ELF 32-bit MSB executable, PowerPC or cisco 4500,
version 1 (SYSV), statically linked, with unknown capability 0x41000000
= 0x11676e75, with unknown capability 0x10000 = 0x90402, not stripped

.config and dmesg: http://nerdbynature.de/bits/2.6.34-rc7/kexec/

make bzImage, not war
