I already had FreeBSD installed on my MSI RS480M2-IL (aka MS-7093)
motherboard, so I installed the patch, remade the modules, rebooted and
tested. Here are the stats:

from 'pciconf -lv':
pcm0 at pci2:1:0:  class=0x040100 card=0x00201102 chip=0x00021102 rev=0x05
hdr=0x00    vendor   = 'Creative Labs'
    device   = 'EMU10000 Sound Blaster Live! (Also Live! 5.1) - OEM from
DELL - CT4780'    class    = multimedia
    subclass = audio
pcm1 at pci0:20:5: class=0x040100 card=0x70931462 chip=0x43701002 rev=0x00
hdr=0x00    vendor   = 'ATI Technologies Inc'
    class    = multimedia
    subclass = audio

pcm0 is a sound card I have been using before the ixp soundchip was
supported.
Net results; snd_atiixp works here (just did a quick test with xmms).
The only thing that I notice is that the output volume is
noticeably lower from pcm1 than from pcm0. I don't know why this is so,
it is just an observation.

Good work!
