IPW2200 and 2.6.14-git

[Alejandro Bonilla Beeche <abonilla@linuxwireless.org>]

Hi, I have an IBM T42 with Debian Sid, since the last kernel-image I 
made Firday 4, November at 7PM EST.

Basically, it would hang so bad that I will not be able to even modprobe 
-r ipw2200

I don't have this problem with another kernel Image that I did like on 
Monday.

This is against 2.6.14-linusGit with the develpment drivers and not the 
inline ones.
