About OMAP-L138 UPP driver‏

I want to use analog input via ADS901 on UI Board of Logic PD's OMAP-L18 EVM on linux. I will develop a Qt application that will draw waveform of analog input. I am using Allan's Linux UPP driver. I compiled UPP driver and load it with inmod command on the EVM.  It is loaded without any problem but graphical LCD is gone away. What can I do to get over this problem? Should I reconfigure kernel?

I also cannot run UPP example application. It gives me an error (19).

Thanks.
