insmod lp problems

[Paul Nathan Puri <"P. Nathan Puri <publisher@ompages.com>"@office.law-counsellor.com>]

When I type 'insmod lp' I get the following error:

office:/# insmod lp
/lib/modules/2.2.0/misc/lp.o: unresolved symbol parport_ieee1284_nibble_mode_ok_Re0d9ee9d

Can someone help me with this?  Thank you.  (I have no idea what any of this means).
