Correct - the touchscreen is enabled via the dtb configuration.  But, 
the default option when ARCH_BCM_IPROC is selected should have the 
driver enabled.  This avoids having to hunt around and turn on drivers 
after the upper level Kconfig options are selected.  Goal is to make it 
easy for user to get their kernel running by having defaults set 
appropriately.  If user wishes to optimize kernel size they can turn off 
drivers they do not need for their board.
