Well, like I said, no way for me to compile this yet but here's the CODE for a modded mini for vWii (theoretically)

It should compile into armboot.bin that you could use on a Wii or vWii to run BootMii as long as there's a BootMii IOS or other way to load it (just that it would be unable to load System Menu, HBC or other channels because it usually uses Boot2 to do that.)
I haven't looked to see if Linux builds use the same mini that bootmii does (in which case, just compile and replace) or a modded version (in which case these same adjustments would have to be made to it) but if the bootmii gui comes up when armboot.bin is replaced with this, we're definitely on to something.
After compiling and testing it on my normal Wii I'll PM the link with the compiled version to whoever wants it.
