I've experienced the same problem with kernel 2.2.6. Parport and lp
support (and paride, ppa support) are compiled as modules.

I could fix the problem by adding the following lines to

alias parport_lowlevel parport_pc
options parport_pc io=0x378,0x278 irq=7,auto

Using the command 'modprobe lp', you should get the following messages
in /var/log/messages (or use the command 'dmesg' to display it):

parport0: PC-style at 0x378, irq=7 [SPP,ECP,ECPPS2]
parport0: no IEEE-284 device present.
lp0: using parport0 (interrupt-driven).

Well, it worked for me, maybe it works for you too.

Cheers, Tobias
