I (the user) am currently connecting successfully with CRDA to a hidden
essid AP.  I previously had claimed that it was still not working, even
though the iw channel output looked good, but it currently seems to be
okay.  I may have previously done something wrong, such as not
rebuilding CRDA for the current kernel, although in that case I'm not
sure why the iw output would have been correct.  In any event, at this
point it seems that it may have been some mistake on my part.  Thanks
for the help, sorry for the noise, and I'll report back if I see any
more trouble.
