  Modified files:
    sys/dev/sound/pci    atiixp.c 
  Log:
  Misc. fixups:
  
  - [1] Make the driver friendly towards kernel without PREEMPTION.
    Use msleep(9) instead of simple unlock-check_variable-lock mechanisme
    since the later not really effective in non-preemptible kernel
    (especially during codec detection routine).
  - Free most driver resources in a sane manner to avoid possible
    double free and panics especially during device detach and codec
    detection failure.
