			* AMD AMD768, AMD8111
			* ALi m5455

    ac97_clock	  - AC'97 codec clock base (0 = auto-detect)
    joystick      - Enable joystick (default off)
    mpu_port      - MPU401 port # (0 = disabled, 0x330,0x300)
    ac97_quirk    - AC'97 workaround for strange hardware (-1 = default)
                    -1 = default, don't override
                     0 = disable
                     1 = use headphone control as master
                     2 = swap headphone and master controls
                     3 = for AD1985, turn on OMS bit and use headphone
                     4 = for ALC65x, turn on the jack sense mode

    Module supports autoprobe and multiple bus-master chips (max 8).

    Note: the latest driver supports auto-detection of chip clock.
    if you still encounter too fast playback, specify the clock
    explicitly via the module option "ac97_clock=41194".

    The joystick and MPU-401 are supported only certain hardwares.
    MPU401 is experimental,  It doesn't work perfectly.

    The ac97_quirk option is used to enable/override the workaround
    for specific devices.  Some hardware have swapped output pins
    between Master and Headphone, or Surround.  The driver provides
    the auto-detection of known problematic devices, but some might
    be unknown or wrongly detected.  In such a case, pass the proper
    value with this option.

    The power-management is supported.
