petitboot

With petitboot running you can boot a Linux kernel from HDD, RBD, USB or network very easily because petitboot has a lot of programs which will allow you e.g. to mount new storage devices
Compiled latest vanilla Linux kernel without init ramdisk and booted it successfully

/etc/kboot.conf

Here is my /etc/kboot.conf for Linux kernels stored on the internal hdd of PS3:

mykernel=/boot/vmlinux-2.6.38-rc4-00154-ga0dc00b-dirty root=/dev/ps3dd1

debian=/boot/vmlinux-2.6.32-5-powerpc64 initrd=/boot/initrd.img-2.6.32-5-powerpc64 root=/dev/ps3da1

custom=/boot/vmlinux-2.6.37-custom initrd=/boot/initrd.img-2.6.37-custom root=/dev/ps3dd1
