I edited the /boot/boot.script manually, and flash the boot image again.
After reboot, I find the correct kernel command in dmesg log.

But when I run totem to play H264 stream, there is a new error:

$ totem XXXXXXX.MP4 
libdce.c:437:    init    info: attempting to open X11 connection
** Message: Error: Could not decode stream.
gstducatividdec.c(1081): gst_ducati_viddec_chain (): /GstPlayBin2:play/GstURIDecodeBin:uridecodebin0/GstDecodeBin2:decodebin20/GstDucatiH264Dec:ducatih264dec0:
process returned error: -1 08008000

When I tried again, there is no error printed. But totem can't play
stream also.

So the HW MM codec doesn't work.

Title:
   OMAP4 Panda: HW MM h/w acceleration doesn't work after installed from
  PPA Update September 2012

Status in OMAP4 Ubuntu Multimedia addons:
  New

Bug description:
  Hi,

  I'm running the official Ubuntu 1204 image on Pandaboard downloaded
  from https://wiki.ubuntu.com/ARM/OMAP/.

  Last month, the HW MM h/w acceleration works on PPA Update August 2012.
  But today HW MM h/w acceleration doesn't work after updating from PPA Update September 2012.
  When running the totem to play a H264 1080p stream, there is an error:

  libdce.c: 437:    init    info: attempting to open X11 connection
  libdce.c: 515:    init    error: could not get plugin ioctl base: -22

  The stream is played very slow because gstreamer is using software
  h264 decoder.

  I updated system following the instruction
  (https://groups.google.com/forum/#!topic/pandaboard/ZnFoQkvD3Pg)
  without skipping a step.
