I heard if you can power on the wii with the wiimotes it's not a bluetooth problem if you can't just change the module like Tealc said.
There are guides on how to do it just use the search...
If you have a look at the image
You'll see just above the SD slot a small card that controls the bluetooth aspect of the Wii. That's Wiimotes, Wiifit boards and any other wireless connected peripherals. If this little card goes pffffft then the System will not load.
I think, because you have both Bootmii and Preloader working, that it has possibility gone pfffft. It's a remarkeable coincidence that it stopped the Wii working when you tried connecting another device to it.
This BLUETOOTH MODULE REPLACEMENT PARTS FOR NINTENDO Wii UK on eBay (end time 22-Jan-10 07:51:45 GMT) is the kind of thing you need to try.
Not really doing much Wii stuff these days.
