Default VIA sound device fails on boot, works with kldload

On my new system, the onboard sound device works if you kldload the module, but not at boot, whether by loader.conf, or built into the kernel.

Here is a screen dump showing the issue.
Code:
[robbak@boffin ~]$ uname -a
FreeBSD boffin 7.0-STABLE FreeBSD 7.0-STABLE #11: Mon Jun 16 14:07:34 EST 2008

[robbak@boffin ~]$ cat /boot/loader.conf
linux_load="YES"
snd_hda_load="YES"
cpufreq_load="YES"

wlan_xauth_load="YES"
wlan_scan_sta_load="YES"

Title  : Great Pretender                 Artist: Stan Freberg

Comment:                                 Genre : Unknown

Directory: /home/robbak/music/mp3/comedy/
Playing MPEG stream from stan freberg - the great pretender.mp3 ...
MPEG 1.0 layer III, 128 kbit/s, 44100 Hz joint-stereo
And I have sound.
Interestingly, at boot, the two pcm devices are detected in the reverse order. This may be significant, because the first pcm device is marked in /dev/sndstat as 'mixer only'. See the following dmesg, and note the memory addresses.
Code:
 dmesg |grep pcm
pcm0: <ATI (Unknown) High Definition Audio Controller> mem 0xfdffc000-0xfdffffff irq 19 at device 5.2 on pci1
pcm0: [ITHREAD]
pcm1: <ATI SB600 High Definition Audio Controller> mem 0xfe024000-0xfe027fff irq 16 at device 20.2 on pci0
pcm1: [ITHREAD]
pcm0: <HDA Codec: Unknown Codec>

pcm1: [ITHREAD]
pcm1: <HDA Codec: Unknown Codec>
pcm1: <HDA Driver Revision: 20071129_0050>
And /dev/sndstat, for completeness
Code:
$ cat /dev/sndstat
FreeBSD Audio Driver (newpcm: 32bit 2007061600/i386)
Installed devices:
pcm0: <ATI SB600 High Definition Audio Controller> at memory 0xfe024000 irq 16 kld snd_hda [20071129_0050] [MPSAFE] (1p:2v/1r:1v channels duplex default)
pcm1: <ATI (Unknown) High Definition Audio Controller> at memory 0xfdffc000 irq 19 kld snd_hda [20071129_0050] [MPSAFE] (mixer only)
Searches have located a few questions like this, but not many answers. I'll hack it by loading the module from rc.conf, but is anything known about this? If I don't get any responses, I'll take it to -questions or -hardware in a few days.
