 Dell Vostro 1400 laptop and using the 159 kernel the lineout does not work.
  If the speakers are plugged in, there is no sound whatsoever and I checked
 every possible mixer setting.  Unplugging the cable to the speakers,
 however, results in sound coming out of the laptop speakers after a
 noticeable pause.  Reverting back to the 134 kernel, these issues go away.

I also have the Dell Vostro 1400. This is fixed in the latest tarball.

However, this laptop also has some other issues:
