El firmware que se descarga de aquÃ

http://sourceforge.net/projects/zd1211/files/

dice que es GPL en el README, pero no queda claro, parece que en
realidad son GPL los headers, pero cuando hablan de "full source"
parece que dentro estÃ¡n los "blobs" y eso no indica si son cÃ³digo o
datos o si se sabe quÃ© significa lo hay dentro:

README
________________
This distribution contains the firmware files for the
ZD1211 chip, which is used in WLAN USB sticks. Copy the zd1211_* files to
/lib/firmware/zd1211, where they can be loaded by the rewritten
zd1211 driver.

The files are generated from C header files distributed in the
original ZyDAS ZD1211 driver under the GNU Public License.

The full source of the original ZYDAS driver is available from
http://zd1211.wiki.sourceforge.net/VendorDriver

The GPL-licensed header files used to produce the firmware blobs are also
present in this distribution. See the COPYING file for the full license
terms.

Si ese, no entiendo bien la verdad, siempre tuve entendido que no era libre,
me acuerdo que lo hice andar en debian etch y el driver lo compilaba pero al
firmware era un binario. Pero me surgiÃ³ la duda verlo en los repositorios de
parabola. En los repositorios de ututo esta?
