What do you mean saying "kernel image"?  zImage, Image, vmlinux,
arch/arm/boot/compressed/vmlinux?

So where do you place your zImage, what is zreladdr, how big is your
RAM?

I'm able to boot with an image having:

	$ git describe
	v2.6.33-rc6
	$ ls -l vmlinux arch/arm/boot/compressed/vmlinux arch/arm/boot/compressed/vmlinux arch/arm/boot/uImage arch/arm/boot/zImage 
	-rwxr-xr-x 1 ukl ptx  2493585 2010-02-02 09:53 arch/arm/boot/compressed/vmlinux
	-rwxr-xr-x 1 ukl ptx  2493585 2010-02-02 09:53 arch/arm/boot/compressed/vmlinux
	-rw-r--r-- 1 ukl ptx  2417764 2010-02-02 09:53 arch/arm/boot/uImage
	-rwxr-xr-x 1 ukl ptx  2417700 2010-02-02 09:53 arch/arm/boot/zImage
	-rwxr-xr-x 1 ukl ptx 49218631 2010-02-02 09:50 vmlinux

Best regards
Uwe
