Thanks for this pointer!  It was the very piece of information I needed.

For anyone else who has been following this thread, here's what I had to
do to get my printer to work with kernel 2.1.95:

I changed the reference to /dev/lp1 in /etc/printcap to /dev/lp0
I added the lines
alias char-major-6 lp
options parport_pc io=0x378
options lp parport=0
to /etc/conf.modules.
I also changed
/lib/modules/2.1.95/misc/lp.o: /lib/modules/2.1.95/misc/parport.o
to
/lib/modules/2.1.95/misc/lp.o: /lib/modules/2.1.95/misc/parport_pc.o
in /lib/modules/2.1.95/modules.dep. 

Hopefully I'll someday find a way to do without that last change.
For some reason, 
post-install parport modprobe "-k" "-s" "parport_pc"
doesn't work for me.

Thanks again to all who helped.

James
