Severe probs with madwifi and FC2

[Peter]

I suffer from severe problems using madwifi for my atheros 5211 card in
my Thinkpad T40p

Using kernel 2.6.7-1.494 I can compile the current CVS tree (with a lot
of warnings), can load the modules but can't establish a connection to
an AP (iwlist can´t detect anything).  Using ATrpms kernel module
madwifi-2.6.7-1.494.2.2-0.8.5.5-7 I can establish a connection, but with
a lot of hardware error messages in messages (curiously only sometimes).

Using kernel 2.6.8-1.521 I can't compile the CVS tree. After applying
the patch mentioned previously on this list, I can compile and load the
module, but again can't establish a connection. Same result using ATrpms
kernel-module-madwifi-2.6.8-1.521-0.9.3.1-11.rhfc2.at. 

Trying to use driverloader with kernel 2.6.8-1.5 results in a kernel
panic.

There are no problems using FC1 and kernel 2.4


Did someone else experience such problems and could manage to find a
solution?



Thanks
Peter
