I've had a look around in the udev source code for an idea of how you

sutiable example to examine.  As such I wont be of much use to you with 
in this regard. Something I did note however was that there is at least 
five different quirky drivers that are using the 0x0ffbc0000 HID usage 
page (defined as HID_UP_LOGIVENDOR), a handful of which do nothing more 
than capture the keypresses from this usage page.  Comparing the keys in 
question I realised that they could have been captured under a single 
quirky driver, if not in hid-input itself.  It appears to me that a new 
generation of Windows MCE remote devices are coming onto the market that 
are using this usage page as standard.  I was going to fiddle around 
with this but instead will wait to see how this will be implemented in 
udev. Sorry I couldn't relieve some of your work-load.

udev keymaps are described in README.keymap.txt in udev package. You can 
find current version on 
http://git.kernel.org/?p=linux/hotplug/udev.git;a=blob;f=extras/keymap/README.keymap.txt;h=9c2d5dc16a151d57720b1dfe39e784f1b1d47367;hb=HEAD
