I just took an image and did a grep -ri tdma and got the following results:

Übereinstimmungen in Binärdatei ./usr/lib/libpcore.so.4.0.0.
Übereinstimmungen in Binärdatei ./usr/sbin/iw.
Übereinstimmungen in Binärdatei ./lib/modules/3.8.6/mac80211.ko.
Übereinstimmungen in Binärdatei ./lib/modules/3.8.6/pdwext.ko.
Übereinstimmungen in Binärdatei ./lib/modules/3.8.6/cfg80211.ko.
Übereinstimmungen in Binärdatei ./lib/modules/3.8.6/ath.ko.
Übereinstimmungen in Binärdatei ./lib/modules/3.8.6/pnwext.ko.

Looks like they at least modify GPLd iw, ath9k and mac80211 code or am
I wrong here?
