I've made major changes to the "ym" (YAMAHA OPL3-SA3) audio device driver.
I'd like to commit this, and can someone check this, Lennart? :)
MD5 (ym-19990921.diff.gz) = cddd6d48769ab908bb0eec0c1a9a55c3

Major enhancement:
	o non PnP attachment at ISA (fix PR kern/5722)
	o "mpu at ym", "opl at ym" attachment (mpu stuff is NOT tested)
	o power management

Major changes:
	o use OPL3-SA3 master volume instead of WSS mixer
	  for "audioctl play.gain"
	o make ad1848_isa CODEC mute while playback is inactive
	o add power control hooks in opl, mpu, and ad1848_isa drivers

Major problems:(
	o loud click noise on power on/off the chip
	o DMA ring buffer overrun (?) on some condition
