The idea is that when a machine is multiuser, the operating system is a layer on top of the machine. So a program should not be able to access hardware IO ports directly.
Even as root. Because eventually you run a program as root, which gets holed, and now that program can access more than the abstract machine, it can touch IO ports. It is ridiculous to permit such behaviour when basically nothing needs it. So, the changes we made are intentional. That software is doing something we don't wish to support.
