I have an HP dv6500 laptop, and I can confirm that the DVD key doesn't work.
Following this page (https://wiki.ubuntu.com/Hotkeys/Troubleshooting) this is a bug in hal because the keycode is greater than 255.
Indeed, xev cannot detect anything, but input-events do :
$ sudo input-events 5
/dev/input/event5
bustype : BUS_I8042
vendor : 0x1
product : 0x1
version : 43841
name : "AT Translated Set 2 keyboard"
phys : "isa0060/serio0/input0"
bits ev : EV_SYN EV_KEY EV_MSC EV_LED EV_REP
