Just to update everyone who's interested, I've managed to run through the Wii Network Guide to further test this out. I now have a working Wii internet connection in Dolphin, but the patch wad doesn't work. It appears to require working access to the Wii Shop Channel to download extra files (it even says that if you ever delete the Wii Shop Channel after patching, your Zelda save will be deleted as well). Since Wii Shop Channel doesn't work in Dolphin, all I get is an error message. So no go on this.
