A few notes on how to get the linux gamecon driver loaded in SuSE 10.0 on a second parallel port.

1. First, I needed to configure the lp module to only install on parport0.  In /etc/modprobe.conf, there was a line that installed parport && lp.  I changed it to this:
   

   install parport /sbin/modprobe -i parport && /sbin/modprobe -i lp parport=0,none,none
   

   Notice the parport=0,none,none.  This says to install lp on parport0, and nowhere else (none,none=not on parport1 or 2).

2. At first I thought to add a line for gamecon in modules.conf, but that wasn't working on boot for some unknown reason.  So I found that SuSE has a joystick init file.  Using YaST, I set joystick to start on boot.  I then edited /etc/sysconfig/joystick, and set the following two options:
   

   JOYSTICK_MODULE_0="gamecon"
   JOYSTICK_MODULE_OPTION_0="map=1,2,2,1,1,0"
   

See the joystick-parport documentation that is part of the kernel-docs package to learn what the map= parameter is all about.

Now, *finally* I can use my nes/snes controller set in linux without having to manually install the module every time (and, unload lp)!  Hooray!
