Yes, if the parport and the lp modules are loaded.

They get filled with some info by the kernel if it finds the devices or
the hardware. You do not edit them.

Do you have the lp.o, parport.o, parport_pc.o and parport_probe.o (last one
is maybe not needed, the others are essential) in /lib/modules/2.2.12/misc ?

Hope so.
Check your modules settings. You need to have:
alias parport_lowlevel parport_pc
in /etc/modules.conf and maybe:
options parport_pc io=0x378,0x278
also.
If you load the parport module, lsmod should show something like this:
Module Size Used by
parport_probe 3204 0 (autoclean)
parport_pc 5828 2 (autoclean)
lp 4644 0 (autoclean)
parport 7048 2 (autoclean) [parport_probe parport_pc lp]
