Thinkpad 600E sound in 4.6-Stable?

Hello all!  A bit of archive searching has hinted quite
often at CS4610/11 sound chips working in FreeBSD-4 with
a bit of tweaking.  I've had no luck.

Machine: Thinkpad 600E 366mhz, 2645-4AU.  DOS-mode PS2
config for audio at port 530, irq 5, dma 0, dma 1,
sb port 220.  (If anyone needs a bootable ISO-image
with the IBM ps2 config utilities, let me know -- 
running a FreeBSD-only shop is a pain at times ;).

OS: 4.6-STABLE FreeBSD Sun Aug 25 19:25:42 EDT 2002

here are all the kernel config bits I've tried:

  # having this doesn't affect anything one way or other
  # and just generates lots of PNP error messages at boot:
  #  unknown: <PNP0501> can't assign resources 
  #options PNPBIOS

  # this probes but no audio
  #device pcm0 at isa? port 0x530 irq 5 drq 0 flags 0x11

  # same thing
  #device pcm
  #device csa0 at isa? port 0x530 irq 5 drq 0 flags 0x11

  # same thing
  #device pcm
  #device sbc0 at isa? port 0x220 irq 5 drq 0 flags 0x11

  # same thing
  #device         pcm0    at isa? port 0x52c irq 5 drq 1 flags 0x10

  # same thing
  #device pcm
  #device         csa0    at isa? port 0x52c irq 5 drq 1 flags 0x10

  # no go
  #device snd0
  #device sb0      at isa? port 0x220 irq 5 drq 0

Here's the most hopeful dmesg probe I can get it to do:

csa0: <CS4610/CS4611> mem 0x50000000-0x500fffff,0x50100000-0x50100fff irq 11 at device 6.0 on pci0
csa: card is Unknown/invalid SSID (CS4610)
device_probe_and_attach: csa0 attach returned 6

Some folks have reported that audio works with this type of suspicious
probing, but I haven't had any luck with any actual audio output.

With MAKEDEV on either snd0 or snd1, mpg123 returns "Can't open /dev/dsp!"

I tried the previously posted fix to /usr/src/sys/conf/files with
exactly the same results, although Kevin Oberman's very encouraging
post from earlier this year says this fix is now unnecessary:

Any suggestions?

Thanks much!
