Crash kernel x86-32: BzImage is not relocatable. Can't be used as capture kernel.

[Pedro Francisco]

I'm trying to debug a spurious condition from which I can trigger a
kernel crash from which no recovery is possible in most cases
(context: http://comments.gmane.org/gmane.linux.kernel.wireless.general/95588
).

Since I can't reliably trigger it, I've decided to use a crash kernel
for when it does happen again, I'm able to get some useful info.

However, on x86-32 I get:
-snip

'--command-line=BOOT_IMAGE=/vmlinuz-3.5.3-1.fc17.i686

--initrd=/boot/initramfs-3.5.3-1.fc17.i686kdump.img
/boot/vmlinuz-3.5.3-1.fc17.i686
BzImage is not relocatable. Can't be used as capture kernel.

+ '[' 255 == 0 ']'
+ /usr/bin/logger -p info -t kdump 'kexec: failed to load kdump kernel'
+ return 1

Any idea if this is possible to workaround?
http://forums.fedoraforum.org/showthread.php?t=282406 says "And bad
news: x86-32 couldn't be recompiled as relocatable. This option
automatically disabled at compilations" but I'm hoping there is some
way to workaround this...

Thanks in Advance,
