Do you mean change the ioport a driver uses by ioctl or actually read/write an
ioport directly?

Do the following patches that I've already posted address your issues:

http://git.kernel.org/cgit/linux/kernel/git/dhowells/linux-fs.git/commit/?h=efi-lock-down&id=c67c338dd82d28c67d38eb3147368eb36dbf1c16

They're going to be in a patchset that I am/was intending to sit atop the
module parameter-lockdown patchset.
