Assuming your Xorg server is configured via hal, you can place a file in 
/etc/hal/fdi/policy/ that removes the driver key.

I use the following file to suppress a joystick from being recognized as an 
X11 input device:

<?xml version="1.0" encoding="ISO-8859-1"?>
<deviceinfo version="0.2">
    <match key="info.capabilities" contains="input">
      <!-- Match on anything you like from lshal -->
      <match key="input.product" contains="SomeProduct Identifier">
        <remove key="info.capabilities"/>
        <remove key="input.x11_driver"/>

Similarly you could use an fdi file to instruct Xorg to use your own input 
driver. Have a look at the fdi files provided for e.g. synaptics touchpads.
