That legacy kernel is FEX (allwinners own description blob) based, I don't know to what extent that involves ATAGs in some way though. There are also people who use the 3.4 based fork from linux-sunxi.org, but I don't know if that is DT or ATAGS or FEX. A dependency on CONFIG_OLD_SUNXI_KERNEL_COMPAT might be an option depending on what the kernels need, Hans probably knows better than I do.
