hewlett-packard keymap for Presario CQ60

whilst fixing my touchpad disable key on my own craptop, i discovered gnome-settings-daemon doesn't even bind separate enable/disable key events, just toggle. so the following are at best broke:

ohsix@krang:/lib/udev/keymaps$ grep 0xD[8-9] hewlett-packard*
hewlett-packard-2510p_2530p:0xD8 f23 # touchpad off
hewlett-packard-2510p_2530p:0xD9 f22 # touchpad on
hewlett-packard-pavilion:0xD8 f23 # touchpad off
hewlett-packard-pavilion:0xD9 f22 # touchpad on
hewlett-packard-tx2:0xD8 f23 # Toggle touchpad button on tx2 (OFF)
hewlett-packard-tx2:0xD9 f22 # Toggle touchpad button on tx2 (ON)

what follows is background on what i did to fix up a keymap for mine

i was getting events from keymap -i that looked like this
enabled -> disabled
got scan code event 0xD8 without a key code event
got scan code event 0xD8 without a key code event

disabled -> enabled
scan code: 0xD9 key code: help

so i mapped them to on/off as above, didn't work; checked /apps/gnome_settings_daemon/keybindings saw that it only bound toggle, set them both to f21 (toggle), it then worked.

the touchpad disable key has worked in the past, what i suspect happened is that xorg at one time translated on/off events to toggle events, or that g-s-d at one time caught both or all 3

afair since last looked into, there are now TOUCHPAD_* key codes in input.h, i did not try them.

as an aside, why aren't the keymaps being submitted upstream as suggested the user do in /usr/share/doc/udev/README.keymap.txt.gz? i've seen the same keymaps for quite a few releases
