I remember hearing that 1.x had /no/ plans for kernel level auto-detection ever. That can be accomplished in early-userspace leaving the code in the kernel much less complex, and therefore far more reliable.
In other words, 'auto-detection' for 1.x format devices is using an initrd/initramfs. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
