 *
 * 26-11-1999 Patched to compile without ISA PnP support in the
 * kernel - Daniel Stone (tamriel@ductape.net) 
 *
 * 06-01-2000 Refined and bugfixed ISA PnP support, added
 *  CMI 8330 support - Alessandro Zummo <azummo@ita.flashnet.it>
 *
 * 18-01-2000 Separated sb_card and sb_common
 *  Jeff Garzik <jgarzik@mandrakesoft.com>
 *
 * 04-02-2000 Added Soundblaster AWE 64 PnP support, isapnpjump
 *  Alessandro Zummo <azummo@ita.flashnet.it>
 *
 * 11-02-2000 Added Soundblaster AWE 32 PnP support, refined PnP code
 *  Alessandro Zummo <azummo@ita.flashnet.it>
 *
 * 13-02-2000 Hopefully fixed awe/sb16 related bugs, code cleanup
 *  Alessandro Zummo <azummo@ita.flashnet.it>
 *
 * 13-03-2000 Added some more cards, thanks to Torsten Werner.
 *  Removed joystick and wavetable code, there are better places for them.
 *  Code cleanup plus some fixes. 
 *  Alessandro Zummo <azummo@ita.flashnet.it>
 * 
 * 26-03-2000 Fixed acer, esstype and sm_games module options.
 *  Alessandro Zummo <azummo@ita.flashnet.it>
 *
 * 12-04-2000 ISAPnP cleanup, reorg, fixes, and multiple card support.
 *  Thanks to Gaël Quéri and Alessandro Zummo for testing and fixes.
 *  Paul E. Laufer <pelaufer@csupomona.edu>
 *
 * 06-05-2000 added another card. Daniel M. Newman <dmnewman@pobox.com>
 *
 * 25-05-2000 Added Creative SB AWE64 Gold (CTL00B2). 
 * 	Pål-Kristian Engstad <engstad@att.net>
 *
 * 12-08-2000 Added Creative SB32 PnP (CTL009F).
 * 	Kasatenko Ivan Alex. <skywriter@rnc.ru>
 *
 * 21-09-2000 Got rid of attach_sbmpu
 * 	Arnaldo Carvalho de Melo <acme@conectiva.com.br>
 *
 * 28-10-2000 Added pnplegacy support
 * 	Daniel Church <dchurch@mbhs.edu>
