Sound on amd64

[Malcolm Kay]

I've just installed FreeBSD-5.3-amd64 on an Athlon64 3200 
and GA-K8VT800 motherboard.

The kernel modules, in contradiction to the handbook, seem 
not to contain any named snd_*. Nor can I find any clues in
/usr/src/sys/amd64/conf/NOTES on how the kernel or modules
for sound support are to be included.

Some selected dmesg lines:---------------------------------
pcib0: <ACPI Host-PCI bridge> port 0xcf8-0xcff on acpi0
pci0: <ACPI PCI bus> on pcib0
pcib1: <PCI-PCI bridge> at device 1.0 on pci0
pci1: <PCI bus> on pcib1
pci1: <display, VGA> at device 0.0 (no driver attached)

pci0: <serial bus, USB> at device 16.4 (no driver attached)
isab0: <PCI-ISA bridge> at device 17.0 on pci0
isa0: <ISA bus> on isab0
pci0: <multimedia, audio> at device 17.5 (no driver attached)

And from 'pciconf -lv':--------------------------------------
none1 at pci0:17:5:        class=0x040100 card=0xa0021458 chip=0x30591106 rev=0x60 hdr=0x00
    vendor   = 'VIA Technologies Inc'
    device   = 'VT8233/33A/8235/8237 AC97 Enhanced Audio Controller'
    class    = multimedia
    subclass = audio

Any help would be appreciated.
