I know that I wrote a program which required I/O privileges at some
point, and it called ioperm() in a setuid wrapper. This was in the late
90s. I suspect we'd have to do a bit of a deep dive to double-check;
the old ioperm() code which only supported the ISA port range to avoid
having to copy the bitmap might be good to look at.
