alps_hw_init_v6  can be reduced at following commands:

static int alps_hw_init_v6(struct psmouse *psmouse)
{
        struct ps2dev *ps2dev = &psmouse->ps2dev;
        unsigned char param[2];

        ps2_command(ps2dev, NULL, PSMOUSE_CMD_SETSTREAM);

        param[0]=0x64;
        param[1]=0x28;
        ps2_command(ps2dev, &param[0], PSMOUSE_CMD_SETRATE);
        ps2_command(ps2dev, &param[1], PSMOUSE_CMD_SETRATE);

        return 0;
}


The Windows driver for latitude E6x30 probably check the DMI
