I'm going to be using iwl5000 which depends on iwlwifi, iwlcore,
iwlwifi-leds, and iwlwifi-rfkill .

So, in short, all I have to do is this?
#!/bin/bash
for a in `find ~/compat-wireless-2.6-old -name '*.c' -or -name '*.h'`; do
sed -e 's/list_splice_tail/list_splice_tail27/' -i $a;
done

The only thing I see as possibly problematic is
list_splice_tail27_init() (sed is regex after all).
