well
i have checked kp-bootimg and it's depends

looks like i missed something
and your write fixing the existed packages is better than creating a new one as i have not used u-boot before didn't know the usage of kp-bootimg with u-boot till now
used to create my own .menu with multiboot only

anyway
i will fix all batterypatch version @extra-devel as soon as i have a free time
thanks for bringing this up
