Sarjaportti ongelma gentoossa

En saa lp porttia ladattua eli modprobe lp antaa messagen:
FATAL: Error inserting lp /lib/modules/2.6.10-gentoo-r6/kernel/drivers/char/lp.ko): Input/output error.

dmesg ilmoitus: lp: unable to get major 6

ls -l /dev/lp: sanoo
crw-rw---- 1 root lp 6, 0 Feb 23 2004 /dev/lp0
crw-rw---- 1 root lp 6, 1 Feb 23 2004 /dev/lp1
crw-rw---- 1 root lp 6, 2 Feb 23 2004 /dev/lp2

Sitten kokeilin tämmöstä:

dmesg >/tmp/a
grep lp /tmp/a

sanoo seuraavaa:
