GameCube Imports on a Wii with no mod or Freeloader? No Problem!
Play import GC games on your Wii with no modification or software
So you want to play GameCube imports on your Wii but don't want to mod your console or buy freeloader? No problem!
One clever person has discovered a disk swap method that allows you to do just that! No hardware modification or additional software is needed. For the moment this swap method is confirmed working on PAL Wii's (it could quite possibly work on NTSC Wii's) using original GameCube titles of another region. However Wii imports don't appear to work using the method. Here's what you have to do:
Insert a GameCube game from your region into the Wii.
Go to the Disc Channel and hover your cursor over the Start button (keep it on the Start button).
Eject the GameCube disc, the Start button should remain active for a brief second, press it.
Quickly insert a GameCube disc from another region (you have very limited time).
If done correctly you should be able to boot the import GameCube game. Apparently this only works with GameCube games as the Wii takes a moment to switch to GameCube mode. The original disk from your region tricks the Wii into thinking it just booted a game with your region. Enjoy playing your imports!

I haven't tried this yet.. so I can't confirm it. But the source(s) seems reliable.
