[Arm-netbook] motherboard negotiation

[lkcl luke]

ok, separate discussion

i'd taken into consideration being able to identify motherboards, by
putting in an I2C EEPROM.  various ideas included having a USB-like
"category / class" thing, and also the idea of putting the linux
kernel device tree data directly into the I2C EEPROM had occurred to
me.

other than that: the exact implementation details are up-for-grabs.

thoughts anyone?

l.

p.s. yes there's fun and games involved in suspend, remove-card,
insert-card, resume....
