I am not having a problem with that here.
grep -i parport /usr/src/linux/.config
CONFIG_PARPORT=m
CONFIG_PARPORT_PC=m
# CONFIG_PARPORT_OTHER is not set
CONFIG_PNP_PARPORT=m
CONFIG_PARIDE_PARPORT=m
/etc/config.modules
alias parport_lowlevel parport_pc
/etc/lilo.conf
Image = /boot/Slink-2.2.10
label = Slink2.2.10
Root = /dev/hdb2
VGA = 0x317
append = "hdd=cdrom lp=parport0 parport=0x378,none"
I am polling the LP so I save in IRQ.
HTH, YMMV, HAND
