Using the keyboard to enable USB booting

Hi,

I need help with a change to the NanoNote board. I want to route the 
boot pins from the CPU (BOOT_SEL0/pin146 and BOOT_SEL2/pin145) so that 
you can just press the 'u' key<KEYOUT7, GPC16 & KEYIN3, GPD20> when 
pressing the power ON button to enable USB booting.

Unfortunately BOOT_SEL0 needs to be GND and I don't have a good idea how 
to easily connect the boot pins into the keyboard.

Does anybody have an idea?
