	* ymf_sb.c: Add 'master_vol' module parameter to change
	'PCM out Vol" of AC'97.
	Should I support AC'97 mixer by implementing original mixer
	codes... ?

	* ymf_sb.c: remove native UART401 support. External MIDI port
	should be supported by sb_midi driver.

	*ymf_sb.c: add support for SPDIF OUT. Module parameter
	'spdif_out' is now available.
