OK, that's better that what I did:  I put it
in /etc/pm/config.d/defaults
(there is no more any manual for pm-suspend.1, just a README which is
not distributed with standard distributions and which doesn't really
explain this in details).

With your /etc/pm/config.d/madwifi file, does it mean that the module
will be unloaded only when it is already loaded (that does not matter
so) but loaded after resuming only if it was loaded before (ie not
systematically).

Any reason why ath_pci doesn't resume? About 2 years ago, kernel people
screened all modules in order to make them suspending and resuming
correctly. And it worked. Why not ath_pci, proprietary code ?
