And here is the init script I run to configure the keys#
# (1) If pressing a key produces the following in the console & syslog
#
# Use 'setkeycodes e012 <keycode>' to make it known.
#
# (2) in the linux sources look for the following table in
# the file drivers/char/keyboard.c
#
# static unsigned short x86_keycodes[256] =
# { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15,

# (3) Search for the value corresponding to e012 which means 256+0x12=273.
#
# (4) In that case x86_keycodes[152]=273 so we need to execute
#
# setkeycodes e012 152
#
# (5) If the value is missing in the table then pick a new one.
# This is the case for e011 for which I use a different mapping
