(I'm using it myself in a t61)

Hmm, yes, that file is not there. Maybe the kernel is too new or too old
for that driver? Or maybe it needs a custom version of mac80211?

... later ...

I started a kernel build to test, and yes, the kernel source includes
that file but most probably it is an "internal" header file that is not
normally needed to build external modules (but is needed in your
particular case):

# find . -name ieee80211\*.h

./include/linux/ieee80211.h
