Hi there, 

I haven't found this one in the archives, please be gentle on me if I
have overlooked something. 

I'm on Debian 3.0, and with it's stock kernel 2.4.18, hostap-driver
0.1.2 compiles, installs, and works just fine. 

Now I have switched to Adrian Bunk's precompiled packages


With this configuration, hostap-driver 0.1.2, as well as the CVS
version as of today, compiles and installs fine. Bu when trying to
load it, I get the following errors, according to dmesg:
