Well, there are no error messages as per se.  As I mentioned earlier,  
booting the kernel installed by the rpm-pkg results in:

kboot: testing
get memory ranges:1
Invalid memory segment 0x800000 - 0x9fdfff
get memory ranges:1
Invalid memory segment 0x800000 - 0x9fdfff
Segmentation fault
kboot:

And that was because I was using an invalid kernel (again, the one  
installed by rpm-pkg):

ps3:~> file /boot/vmlinuz*
/boot/vmlinuz-2.6.21-rc5-20070330: ELF 64-bit MSB executable, cisco
7500, version 1 (SYSV), statically linked, stripped
/boot/vmlinuz-2.6.21-rc7-20070418: ELF 32-bit MSB executable, PowerPC
or cisco 4500, version 1 (SYSV), statically linked, not stripped

I may be able to debug this on Monday.
