As Sean says, could be a corrupted download. Try running md5sum on the zimage file.

My copy of v151, which has been successfully installed, returns the following from md5sum: \3bca07933c8a23ab5dee7cb68a7563b9 (not sure if the \ is supposed to be part of the sum or not, but if the rest matches you're OK)

Do you have any odd stuff in config.ini?
