As part of the work that Mark et al did for NCI to get the dynamic
linking
of libraries working, LKMs sort of fell out in the wash. I believe those
of us that are running RiscBSD 1.2G (the limited release soon to be made
'production'), already are using LKMs without realizing it - I didnt
check
but just before it was released for testing the least version I had used
LKMs for msdos disks.

I believe you can do this in the same way that you write directly to the 
serial port. Take a look at the READ and WRITE macros in the kernel. As 
I understand it these are just mappings to the raw IO stuff so they
should
be able to access the parallel port.

Hrm, this sounds like its probably going to be through one of the
ioctl's but
no idea which one...
