Jason you are right  

this are the steps
in .filetool.lst -->   lib/modules/2.6.26-tinycore/net
in bootlocal.sh: -->  depmod -a
                        -->  modprobe ath_pci
in Control Panel -- Netcardconfig --  Interface --> ath0
                                                 -- Nameservers --> one or two IP's for resolv.conf
                                                 -- Save Configuration? --> yes
                                                 -- Aply and Exit
If you look now to bootlocal.sh you see in the last line:
/opt/ath0.sh &
Now after rebooting:
lsmod
and you see the loaded modules from ath
to finish:
sudo ifconfig ath0 up
sudo iwconfig ath0 essid "your essid"
and finally Minefield and surf the net
¡Great!
