Another brain fade.  I really must get out of holiday mode.

Find attached two revised patches against alsa-driver hg snapshot from
20080107:

 * alc260-test-eapd-0.2.diff

   This implements a switch control for the EAPD signal output by the ALC26x
   chips.  Since some laptops may utilise this to activate useful things it
   is handy to have a control for this in the ALC26x test models.  The patch
   includes the control in the ALC260 test model.

   Signed-off-by: Jonathan Woithe <jwoithe at physics.adelaide.edu.au>


 * alc268-test-0.4.diff

   This implements a test model for the ALC268.  It depends on the feature
   added by alc260-test-eapd-0.2.diff.  This patch also adds a mention of
   the ALC260 test model to ALSA-Configuration.txt since this seems to have
   been missed.
