5.3-BETA2 panic on qemu

	Sorry, I don't have *realy* Sound Blaster16.  This is about
	*virtual*(=qemu) Sound Blaster16.  So I don't know true or false
	alert.

	[ENVIRONMENT]
	FreeBSD 5.3-BETA2 on QEMU 0.6.0-2004-08-26_23.
	KERNEL is GENERIC

	[uname -a]
	# uname -a
	FreeBSD  5.3-BETA2 FreeBSD 5.3-BETA2 #1: Sat Aug 28 21:29:15 UTC 2004   root_at_mack.dcsl.buffalo.edu:/usr/obj/usr/src/sys/GENERIC  i386

	[I did]
	I play a wav file. As soon as panic: SEE ALSO:

	hint.sbc.0.at="isa"

	hint.sbc.0.irq="5"
	hint.sbc.0.drq="1"
	hint.sbc.0.flags="0x15"
	snd_sb16_load="YES"


	And, I think that there is a problem in /usr/src/sys/conf/NOTES.
	Are following lines collect?
- - - - - - - - - - - - - - -
hint.snd_sbc.0.at="isa"
hint.snd_sbc.0.port="0x220"
hint.snd_sbc.0.irq="5"
hint.snd_sbc.0.drq="1"
hint.snd_sbc.0.flags="0x15"

	In this case, FreeBSD didn't probe SB16.
