Hmm, I guess here is the reason:

actions sequence

action                           radio status

1. system boot                                            
2. Fn + F5 pressed                     off
an hotkey interrupt send to processor    
3. wireless modules loaded            
  disable radio by default              off
4. interrupt handling for Fn+F5
  switch the status of radio            on

Again, I recommend the users who want the wireless is on when booting do
these jobs:

touch /etc/rfkill/defstate
echo 1 > /etc/rfkill/defstate

and put this line into /etc/rc.local

cat /etc/rfkill/defstate > /sys/rfkill/rfkill0/state

and in the future, hope a new interface will be added by the
NetworkManager(or gnome-power-manager/kpowersave) maintainers to allow
users to configure the default booting status of rfkill. and even record
the last status in /sys/rfkill/rfkill0/state

This has no relation with the kernel part, attached two config files,
which may fix this issue.

And also, no problem with my debian 6.0. there are four available
choices(60,70,73,75) provided by gnome-display-properties.
