I believe the patch is fundamentally wrong. We don't *need* to drop the IO decode in this case. We don't want to drop it when the BIOS lacks the brains to put it back. We will also kill some machines doing it as they have devices we attach drivers to which are not just managing the function Linux knows about but also many other things. Take the CS5520 for example, generically disable the I/O on that because we have an IDE driver attached to it and you kill the box stone dead, as its also the video and a few other things behind the scenes. That is not atypical.
IFF someone has a device that actually needs to disable I/O cycles, well they can do it themselves.
