The kernel now boots where it booted for my 64bit box.

The main problem though is the instant reboots for bzip2 and lzma
compressed initramfs images. The change for printf to /usr/bin/printf
both render the sane end result when run with the same commandline being
run in the makefile, so this isn't the issue.
