I can confirm that the user-space firmware loading is broken in Ubuntu
9.10. The linux-wlan-ng package installs udev rules to call /etc/wlan
/wlan-udev.sh when the module is loaded. But /etc/wlan/shared, which
originally was prepared to deal with a large range of cards, looks up
the now non-existing /proc/net/p80211/ to see which driver family this
card is using ("prism2") to call the right firmware loading function
(surprise, there is only one anyway).
As a quick fix, you can apply the below patch.
Alternatively, as suggested in the original report, you can copy
/etc/wlan/prism2_ru.hex to /lib/firmware and then purge all linux-wlan-
ng* packages. This also works fine here.
