Nope, using the module. BTW, loading the if_run module gives

ieee80211_load_module: load the wlan_amrr module by hand for now.

Did exactly that, i.e., loaded the wlam_amrr by hand. Do you think I
might fare better by using in-kernel drivers instead of modules?

Amongst other things, I also did that.

No, it did not panic. After trying to enable wpa, the systems becomes
very sluggish on the network side and recovers upon pulling the dongle.
I interpret that as some kind of crashing the driver.

I would be happy to provide a back trace, I do not know how,
though. Where do I need to look to learn that?

Thanks and cheers, Christopher
