Problem Interfacing with Hal

[Danny Budik]

Thanks for all your help.

I realized that I wasn't calling the main wait loop properly.  I was 
just doing a while(1), whenI should've been creating a loop with 
g_main_loop_new() and then calling g_main_loop_run(). Adding those two 
calls made it work. Now I can just use libhal_device_get_property_int to 
get the info that I need from hal.

Thanks again,
Danny
