Nobody stops you from setting up a GDT entry by your own. The lack of
an appropriate device helper doesn't mean you can't do that. Some years
ago I inserted two call gates into the GDT to implement high speed
access to some driver routines which were meant to be called from user
space with as little latency as possible.
If you need an assembler snippet from that driver just ask.
