Comment 174 for bug 621265

Not joking at all for myself. Not a solution for everyone probably,
but I'm very happy now. I enjoy opening up hardware. Replacing
wireless card is trivial compared to the soundcard replacement I did a
few months ago. :) Main thing is that I'm not even thinking about
this bug anymore and I'm glad about it.
