Embedded Linux Button Support

[Linux Robot]

I'm fiddling with linux on a PDA (the VTech Helio), and was wondering if 
anyone knows how I could go about controlling the buttons at the bottom 
(actually make them do something useful).  Currently I get console messages 
when I press the buttons (which seems to include a unique number for each 
button).  So it seems like linux knows that the buttons exist, and it's just 
a matter of setting up a controller or something...  I tried a few mailing 
lists, but either the links are dead or no one responds to my desperate 
pleas for help.  I was just wondering if anyone here knows how I could start 
tackling this problem, or where I could go to for help...

Thanks,
The Button-Insubordinate Linux Robot
