xorg.conf for touchscreen (imx53)

Hey all,
I'm having some problems getting xorg to behave correctly on a iMX53 touchscreen. When my device first starts X, it switches mouse protocols a few times until it gets to ps/2 (see below), then when I touch the screen the X menu appears momentarily but the cursor never moves and i'm not able to click on anything. I'm using TSLIB, and I am able to run ts_calibrate and ts_test with no problem (draw/drag/drop ok), but that's the only application that allows me to move the cursor and click on the screen. This makes me think it is a problem with the config file xorg.conf. Does anyone have any ideas or suggestions as to what I should try or any hints on what's wrong with the xorg config file below? thanks? Btw, plugging a USB mouse in works perfectly fine.

Output after starting X:
_XSERVTransSocketOpenCOTSServer: Unable to open socket for inet6
_XSERVTransOpen: transport open failed for inet6/iND16599:0
_XSERVTransMakeAllCOTSServerListeners: failed to open listener for inet6
