Are you in X? If you are, try from console.

You could also try debug.debugger_on_panic set to 0. This will make your box
panic insead of going into the debugger.

When unloading snd_hda, the system (v3.1.0.197.gcc1635-DEVELOPMENT) freezes completely.
There is no panic; the screen just gets garbled and the system no longer responds to any interaction, may it be local or via network. 

This shows up when loading the module:

pcm0: <NVidia MCP51 High Definition Audio Controller> mem 0xf2300000-0xf2303fff irq 21 at device 16.1 on pci0
pcm0: <HDA Codec: Realtek ALC260>
pcm0: <HDA Driver Revision: 20071129_0050>
