I am glad that some feature to get this in is now getting in to the standard kernel, but it does strike me that this in-initrd method means that normally you would not have to rebuild your kernel just because you have a buggy DSDT every time you put up a new kernel. Normally these days I can work with the stock Debian kernels, and so I do not need to rebuild the kernel every time. Do you know who decided this and why?
