I just did lots of handwaving. You did the work :)

You've used the inline assembly method. I have a suspicion that
if I used this switching function with the version of gcc that comes
with devkitarm (for GBA and NDS), it would have the stack
register preservation problems I had with the thumb switching
inlined code, and I would have to create a full assembler
routine like there is for thumb. But I think it is probably useful
to have both.
Didn't you have a problem with the stack register preservation
with your version of gcc?
Why do you modify the fp register?
I see you also save r1, r2 and r3. The reason I don't do the same
is that I read somewhere that r0-r3 do not need to be preserved.
Also, they were not used in the assembler version of the inlined
switch which I used as a base.
