 As some of you may know, I'm working on a 501(c)3 (tax exempt/non-profit)

 confused about the nature of FreeBSD and we're currenlty working on
 a response to an initial determination from the IRS that was not
 favorable.  One thing that would help us to explain the nature of
 FreeBSD and how it is used by the public is to enumerate some
 specific examples of how FreeBSD is used as either a teaching
 aid or a research platform by educational institutions.  If possible,
 please include a contact name, email, or phone number so we can
 ask additional questions if necessary.

Re: VibraX audio broken with newpcm

 In my kernel and "pnp aware OS" turned both on and off in my BIOS,
 I get this on probe:
 
 pcm0: Vibra16X at port 0x220-0x22f,0x330-0x331,0x388-0x38b irq 5 drq 1,3 on isa

I'm having the same problem, however, I get drq 0,1 rather than 1,3
since I have ppc0 using drq 3.  It doesn't work if I take ppc0 off drq
3 either.

 But just catting a .au file to /dev/audio (yep, MAKEDEV snd0 run 
 previously) results in the cat hanging and no sound.

Ditto.  Playing mp3s seem to start (i.e., CPU usage goes up but then
stops), then it just hangs and gqmpeg/mpg123 needs to be killed.  

 Just for comparison, from a kernel of August 29th using:
 
 controller  pnp0
 devicepcm0 at nexus? port ? irq 5 drq 1 flags 0x13
 
 I get this on probe:
 
 CSN 1 Vendor ID: CTL00f0 [0xf0008c0e] Serial 0x Comp ID: PNPb02f [0x2fb0d041]
 pcm1 (SB16pnp Vibra16X sn 0x) at 0x220-0x22f irq 5 drq 1 flags 0x13 on isa

That was the last working build for me as well.  I've since downgraded
to 3.3-RC.  Here's the probe from 3.3-RC..

Probing for PnP devices:
CSN 1 Vendor ID: CTL00f0 [0xf0008c0e] Serial 0x Comp ID: PNPb02f [0x2fb0d041]
pcm1 (SB16pnp Vibra16X sn 0x) at 0x220-0x22f irq 9 drq 1 flags 0x10 on isa

And here's my kernel config..

controller  pnp0
device pcm0 at isa ? port? tty irq 9 drq 1 flags 0x10

Which works fine.  I think part of the problem I'm having is that 
newpcm won't find it on it's actual irq, which is 9 instead of 5.
