Using Dvorak with the Microsoft IME for Japanese (or any other language I'd assume)

I figured out a way to do this, I guess others may find it useful as well.

Open up regedit, and go to "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layouts". Inside this key there are multiple other keys with 32-bit hexadecimal values. Notice that "00010409" is "United States-Dvorak", and "00000409" is "US". "00000411" is Japanese. I changed the "Layout File" there to "KBDDV.DLL", as well as the "Layout File" under "E0010411", "Japanese Input System (MS-IME2002)", and now kana input is recognized in dvorak rather than default QWERTY mapping! :)

EDIT: Be warned that this may break たていすかん-style Japanese input (what you get if you click Kana, usually). I can't seem to get it to work, anyway. But if you want to use Dvorak under the IME, I guess you're probably not interested in たていすかん入力 anyway.
