You can generate an exhaustive list of known keycodes with

  grep KEY_ /usr/include/linux/input.h

However, that only means that those key codes are defined, not that
each and every laptop model has completely working keys. The hal-info
package maps scancodes (which are highly vendor, and even model
specific) to their intended meaning (the key codes from above), and in
general coverage is pretty good (see also my efforts on the platform
sprint where I asked everyone with nonworking hotkeys to come to me to
get them fixed).

Another glitch is that X.org currently can only digest key codes below
256; i. e. KEY_MAIL, KEY_REWIND etc. all work, but KEY_FAVORITES
(0x16c), KEY_TV (0x179), etc. cannot be used with X.org programs
(that's an X11 protocol limitation, see LP #313514); they can be used
with LIRC, hal, and other programs, though.

The new notification elements work wonderfully, except it seems that eject
