did that, and did a cold reboot:

% dmesg | fgrep -i hda
hdac0: <ATI SB600 High Definition Audio Controller> irq 16 at device 20.2 on pci0
hdac0: HDA Driver Revision: 20100226_0142
hdac0: [ITHREAD]
hdac0: hdac_get_capabilities: Invalid corb size (0)
hdac0: Resetting corb size to 256
hdac0: hdac_get_capabilities: Invalid rirb size (0)
hdac0: Resetting rirb size to 256
%

I don't think the device attached.
