I wouldn't try installing any of the available roms on the SL-C3000, because (as far as I know) none of them support the 3k yet. The applications might work ok, but I wouldn't count on the kernel working properly.
Also, some of the 3k apps, such as the dictionary, zdict, require newer versions of certain libraries, including libqpe. If you _were_ able to run something like Cacko on the 3k, it would take some work to get the 3k apps to work properly with it (though it is possible).
Btw, it's extremely easy to (re)add Japanese support to a Cacko Qt install... there is a japanese-support ipk floating around that includes all the necessary fonts and files.
