 *
 * This driver is a merge of the Elographics driver (from Patrick Lecoanet) and
 * the driver for Fujitsu Pen Computers from Rob Tsuk and John Apfelbaum.
 * 
 * Modified for Stylistic 3400 passive pen support by David Clay
 * Fixed processing of all packets
 * Detangled and simplified if-statement logic
 * Fixed hover-mode pointer movement
 * Added Passive parameter for passive displays
 * Added switch 3 for "right" mouse button
 * I might have broken active pen support. I can't test it.
 *   January 2005 <dave at claysrus.com>
 *
 * Stylistic 500, 1000, 1200, 2300 Support fixed by John Apfelbaum
 *   June 2001 <johnapf@linuxlsate.com>
 *
 * Richard Miller-Smith <Richard.Miller-Smith@philips.com>
 *
 * Fixed up for XFree86 4.2, cleaned up the junk, cured crash on pointer
 * setting.
 *
