Very early on for 386bsd I implemented ioperms in the kernel mostly for X servers however later on the XFree86 team decided that was not a good approach due to the crazy way that vga controllers were being design with sparse memory mapped io ports. Not sure how linux handles the later case and I doubt that it does.
