  Add a overhaul of the soundchip initialization for the MSP34xx chipsets
  found only many tv-cards.
  We currently use more ore less evil hacks (slow_msp_audio sysctl) to
  configure the various variants of these chips in order to have
  stereo autodetection work.  Nevertheless, this doesn't always work
  even though it _should_, according to the specs.
  This is, for example, the case for some popular Hauppauge models sold
  sold in Germany.
  However, the Linux driver always worked for me and others.  Looking at
  the sourcecode you will find that the linux-driver uses a very much
  enhanced approach to program the various msp34xx chipset variants,
  which is also found in the specs for these chips.
  This is a port of the Linux MSP34xx code, written by Gerd Knorr
  <kraxel at>, who agreed to re-release his code under a
  BSD license for this port.
  A new config option "BKTR_NEW_MSP34XX_DRIVER" is added, which is required
  to enable the new driver.  Otherwise the old code is used.
  The msp34xx.c file is diff-reduced to the linux-driver to make later
  modifications easier, thus it doesn't follow style(9) in most cases.
