I've quickly taken a look, and I can't find the patch.
So here are some info to do it yourself (from a 2.6 tree, so must be adapted
to 2.4):
* the file to modify is named hid-core.c, and should be in
drivers/usb/input/
* you need to add:
- those defines:
#define USB_VENDOR_ID_MGE              0x0463
#define USB_DEVICE_ID_MGE_UPS          0xffff
#define USB_DEVICE_ID_MGE_UPS1         0x0001
- 2 entries in hid_blacklist:
        { USB_VENDOR_ID_MGE, USB_DEVICE_ID_MGE_UPS, HID_QUIRK_IGNORE },
        { USB_VENDOR_ID_MGE, USB_DEVICE_ID_MGE_UPS1, HID_QUIRK_IGNORE },

And that should be good. Don't hesitate to ping me back if not.
