The compaq ku 0133 keyboard has 8 special keys at the top:
http://lackof.org/taggart/hacking/keyboard/cpqwireless.jpg
3 of these use standard HID usage codes from the consumer page, the 5
others use part of the reserved 0x07 - 0x1f range.
This commit adds mapping for this keyboard for these reserved codes, making
the other 5 keys work.
