That's interesting, my cards are actually running a point-to-point link
and are configured in IBSS mode. It had occured to me that maybe the
numbers didn't make sense in IBSS mode, but it used to work so I
wondered why it had changed. I have since tried the card in a Windows
machine running NetStumbler and it gives sensible readings for signal
strength and noise, so the information is apparently still available
from the card somewhere/somehow.

I was getting intermittent lock ups. Initially I was using WEP and
apparently 1.4.9 had some problem with WEP. I've since switched to
IPsec, but was still getting the odd freeze now and then. I haven't
been running the new firmware long enough to know for sure whether it's
made any difference or not.
