No auto-enable WiFi at boot

[David N. Lombard]

I have an Acer Aspire One D150 running UNR 9.04.  All is well in 
general.  My problem is the radio is brought up at boot and a connection 
is always attempted.  I'd like to use the netbook on a plane, but I 
can't unless I can disable the radio.  There's no hardware radio switch.

Ideally, I'd have a grub boot line that disabled the radio--sort of an 
"airline mode boot".  Barring that, I'll be happy disabling the 
auto-radio-init and a way to manually turn the radio on.  Any suggestions?
