I've added this to my local branch for .31 for my HP 2510p.
Light testing (linux only) showed no problems with .31-rc4.

One question: is it expected that pressing the hardware kill switch only 
enables the block for phy0? I guess it's probably sufficient.

$ ./rfkill list # after pressing hardware switch
0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: yes
1: hp-wifi: Wireless LAN
        Soft blocked: no
        Hard blocked: no
2: hp-bluetooth: Bluetooth
        Soft blocked: no
        Hard blocked: no

Looks like with bluetooth soft-blocked the wireless leds blink on wifi 
network traffic, while with bluetooth unblocked it stays on permanently.
