added support for Tablet PCs

Added support for Tablet PCs with these features:
 * identify Wacom and Finepoint Tablet PC devices and port/irq
 * set system.formfactor.subtype to 'tabletpc' this allow the desktop
   to handle special tasks for Tablet PCs as e.g. show OnScreen Keyboard
 * added setserial helper to setup /dev/ttyS* devices with sepcial
   parameter if needed
 * added fdi-file to call for special Tablet devices setserial with
   needed parameter where the kernel can't setup the device correct

This patch is already included in the SUSE hal package since 08/2005.
