Intel ICH3 (82801CA) -- fails to probe as of 13 May 2007

My current laptop is a Dell Inspiron 8200; I track RELENG_6 & HEAD on it
on a daily basis.

FWIW, in general, CURRENT works well for me. :-)

Yesterday, though, I noticed that after I fired up xbiff, I was
assaulted by a very loud beep. A quick reality check revealed that the
little script I had placed in /usr/local/etc/rc.d to perform a

mixer vol 25

did not run because there was no /dev/mixer.

Oh.

Well.... Checking messages from the previous day, I see:

(I put a few lines of merely contextual information both before &
after the Intel ICH3 (82801CA) probe messages.)

Looking at the corresponding region from booting yesterday's CURRENT for
the first time, I see:

May 13 09:51:59 localhost kernel: ata1: stat1=0x3f err=0x3f lsb=0x3f msb=0x3f
May 13 09:51:59 localhost kernel: ata1: reset tp2 stat0=bf stat1=bf devices=0x0
May 13 09:51:59 localhost kernel: ata1: [MPSAFE]
May 13 09:51:59 localhost kernel: ata1: [ITHREAD]
May 13 09:51:59 localhost kernel: pci0: <multimedia, audio> at device 31.5 (no driver attached)
May 13 09:51:59 localhost kernel: pci0: <simple comms, generic modem> at device 31.6 (no driver attached)
May 13 09:51:59 localhost kernel: acpi_tz0: <Thermal Zone> on acpi0

OK; so it looks as if a device is found (flavor "<multimedia, audio>")
on pci0 at device 31.5, but no driver is attached.

Eh. I don't see any changes in src/sys/dev/pci that might have
occurred at a time to accomplish that. Looks as if I could use a
clue as to where to look.

And I'm quite willing to test stuff; I keep a private mirror of the CVS
repo handy.

Thanks!

Peace,
david
