... so you opt to create the big mess in the kernel. Great.

And it does not even fixes a real problem, but getting
mmconfig or the numa bus discovery to work is not really a too serious 
issue anyways. At best it is the icing on the cake to enable
some relatively obscure functionality and be a little more
efficient, but nothing really fundamental.

But for those things just expecting a working modern BIOS is quite
reasonable.
