Very nice. I'm glad to see that you removed all that unneeded complexity.
Please remove "rant" at the end. linux-wlan-ng 0.2.1-pre17 supports
flashless cards, although it has a serious bug in the prism2dl utility.
A workaround is to run firmware files through "sort". I hope the next
version will be released shortly.
It would be much more useful to write something informative about the
status of the linux-wlan-ng driver. HostAP support is still better
because it determines the memory type and whether the card is PCI, while
with linux-wlan-ng you have to write is manually to the initial PDA.

I can reproduce a similar but possibly related problem. If a WEP key is
set and I remove hostap_crypt_wep, iwconfig causes an oops in

Kernel should not crash if you are doing something wrong (short of
unscrewing and removing PCI cards from a working machine). Reference
counting should prevent unloading of the modules that are currently in
