Thanks for the reply.  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?
