ACK, same here. I'm an owner of a 'One A110' mini-laptop (see
http://a110wiki.de/wiki/Wireless) and the situation is really getting
uncontrollable with a gazillion of tarballs and patches for the R8187B
driver floating around, all of them with small differences...

(the ID on this laptop is 0bda:8189 btw)

I'm very interested to see something get merged upstream, and I'm also
willing to test whatever needs testing on my hardware.


Thanks, Uwe.
