Thanks Chunky:

Your confimation about the hat being 2 axis allowed me to hack my
"joydev.c"??? file.  I don't remember exactly what the file name was, but
any way:

MAKE a BACKUP!!!! of joydev.c???

For 2.4.8:
---  Step #1   Add the following line just before the return statment of the
joydev_connect fucntion:
// Makes programs and the driver think you have 4 extra buttons
joydev->nkey +=  4;

--- Step #2   Add the lines similar to the following to the joydev_event
function inside case EV_ABS:
// EV_ABS means AXIS event
static int leftOn  = 1;  // Needed for when you bring collie back to center
static int upOn   = 1;
if (event.number == 4) {    // 4 was the number of my left-right POV axis
event.type = JS_EVENT_BUTTON;  // Fake the computer out tell it we pushed a
button
if (event.value > 0)  {  // Right
    event.value = 1;   // If the person pushes the right pos button set
value to 1 (button pressed)
    event.number = 9;  // The first of the extra buttons added earlier
    leftOn = 0;            // Did the user go left or right?
} else if (event.value < 0) { // Left
    event.value = 1;   // Turn the ficticious button on
    event.number = 10; // One of our fiticious buttons
    leftOn = 1;              // The person when left
} else {   // Person moved hat back to center
    event.value = 0;   // Turn the ficticious button off
    if (leftOn)
        event.number = 10;
    else
        event.number = 9;
} else if    // Use chose up-down axis, map actions to buttons 11 & 12
    // Hopfully you can figure out what goes here, if not, I can mail the
hack to you
    // but it MAY only work for Sidewinder Precision Pro USB on 2.4.8
    // and I don't care if you blow up your computer...
    ...
}

--- Step#3:
cd /usr/src/linux
make modules; make modules_install;

If you didn't get any compile errors, and joydev.c. is a module on your
kernel config.  You can start up Descent and configure your hatswitch for
the slide up, down, left and right functions.   Descent will think that it
is buttons 9, 10, 11, and 12.   Before you define any new actions for your
collie, you might want to clear out the old actions since you might blow up
your computer if you try and use the collie as both an axis and a buttons
switch, anyway...

It worked great for me!!!! and D3 under Linux ROCKS!!!!!
