There are some alphanumeric LCDs out there with RS232 or USB interface.
A medium C programmer can work them out without a driver in a day.
Why the hell do you want to change an entire OS for a
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
i386_get_ioperm() and i386_set_ioperm()
These were removed from sysarch.h between OpenBSD 5.9 to 6.0?
I believe this code (port.h):

On OpenBSD 5.9, it uses the code branch for 'NetBSD/OpenBSD'

You're saying this as if

Is it possible with OpenBSD i386 to use the parallel port for lcdproc?
More specifically:
Did something change at OpenBSD i386 between 5.9 and 6.0
related to parallel port / lpt hardware permissions?
Up to OpenBSD i386 5.9,
I used to be able to have a working case-LCD-screen

You'll need to chown/chmod it narrowly to the uid who wants to use it.
You want to constrain use of the device driver as much as you can.
