Damien Bergamini, ported and submitted by FUKAUMI Naoki per PR kern/30449 I've modified the USB "ural" driver for recent changes to the NetBSD ieee80211 framework, possibly not completely, but with an ASUS wireless adapter I'm getting some signs of life. Didn't care about pci/cardbus for now, hopefully someone with hardware will do it.
