12.04 and earlier ignore "www" key on HP EliteBook 8440p

See also https://bugs.launchpad.net/ubuntu/+source/linux/+bug/749839

In 12.04 and earlier releases back to 11.04 on my HP EliteBook 8440p, key presses of the "www" (globe) key are ignored. Key presses of the other multimedia keys (Mail, Mute, Volume Up, Volume Down) are detected.

The attached rules file fixes the problem, with this addition to /lib/udev/rules.d/95-keymap.rules after LABEL="keyboard_vendorcheck":

    ENV{DMI_VENDOR}=="Hewlett-Packard", ATTR{[dmi/id]product_name}=="HP EliteBook 8440p", RUN+="keymap $name hewlett-packard_elitebook-8440p"
