Joker,
You need a passive sniffer, like Kismet (Unix/Linux-based)
in order to identify a non-broadcast SSID. Most
wardrivers use the Windows-based Netstumber, which is an
active sniffer. I've found my old broadcast SSID (from 1
1/2 yrs ago)in a database lookup on the web. I haven't
found any of my non-broadcast SSIDs.
While I agree that disabling the SSID is not a valid
method for securing a wireless network, it does prevent
the vast majority of casual wardrivers from seeing your
network in the first place. If the network isn't
visible, then they aren't tempted to crack it or connect
to it. I believe that disabling the SSID, used in
conjunction with other methods of securing/masking your
network will help to make your home network as
reasonably secure as it can be.
There is an excellent web-based article on Wireless
Security at
http://arstechnica.com/paedia/w/wireless-
security-howto/home-802.11b-1.html. The article is
titled "Security Practicum: Essential Home Wireless
Security Practices" by Ken "Caesar" Fisher. Another
article is the "Wireless Security Blackpaper" by
Trey "Azariah" Dismukes at
http://arstechnica.com/paedia/w/wireless/security-
1.html. Lastly, check out the "Wireless Networking Basic
Security Checklist" by Frank Thornton (one of the
moderators of the Netstumbler forums):

One extra layer of perceived security shouldn't be
dismissed so readily.
