2.6.11 gentoo r3 kernel

I am having problems with modprobe.
After installing the modules and make; make install; depmod -a
I do
modprobe ath_pci and I get this error message
Fatal: error inserting ath_pci(/lib/modules/2.6.11-gentoo-r3/ath_pci.mod.o): Unknown symbol in module, or unknown parameter

last few lines of dmesg
ath_pci: mosule license 'enspecified' taints kernel.
ath_pci: Unknown symbol "init_module, cleanup_module"

use emerge madwifi instead.

no ebuilds for madwifi, or -driver or -tool/s

You may need to unmask it... run emerge --search madwifi-driver madwifi-tools

run emerge --sync if it's been a long time you didn't run that command
