No mention of it - 2.6.33-rc8.
tindog:~ # dmesg|grep 1043
tindog:~ # grep 1043 /var/log/boot.msg
tindog:~ # grep 1043 /var/log/messages

The patch seems to be addressing the wrong  device, alsa-info.sh shows
it as
        Subsystem: 1043:81f6
Subsystem Id: 0x104381f6
  Components    : 'HDA:11d4198b,104381f6,00100300'

tindog:/usr/src/linux-2.6.33-rc8 # grep 1043 ./sound/pci/hda/hda_intel.c
        SND_PCI_QUIRK(0x1043, 0x813d, "ASUS P5AD2", POS_FIX_LPIB),
        SND_PCI_QUIRK(0x1043, 0x1262, "ASUS W5Fm", 0x103),
        SND_PCI_QUIRK(0x1043, 0x81f2, "ASUS", 0), /* Athlon64 X2 + nvidia */
        SND_PCI_QUIRK(0x1043, 0x829c, "ASUS", 0), /* nvidia */

I shall change the 0x81f2 to 0x81f6 and test.

I think you are correct, could be the motherboard or BIOS. I have tried
a number of BIOS versions with the same result. I am about to change to
a Asus Crosshair III motherboard in a few days when the memory arrives.
It also wouldn't boot if I have kgdb enabled in .config, I get a stream
of Traces with "Tainted".

It's the on-board sound. Before the work around I had to disable it in
the BIOS and use the USB sound card.
