[Voyage-linux] Fwd: Madwifi compile warnings (2.6.38)

[Teco Boot]

X-posting, FYI for Voyage Linux developers.

I decided to fall back to madwifi. Ath5k does not provide
some important functions for me (AHDEMO, TxPower, access to 
Minstrel stats without debugfs). I'll check ath5k again in 
a next update cycle.

Compiling madwifi has some warnings. But I can run it.
Any other experience?

Thanks, Teco
