Are you sure the object file for chprintf got recompiled? Did you "make clean"? I tripped over that when I was trying to get fp output last week.

Wasn't there once an issue with varargs and floating point? Which also never got solved and the "toolchain" got the blame? I'd wager this is the same case.
What is the status of the raspberry Pi Port? I guess it needs a recommended toolchain and working debugging. OpenOCD should support it, right?
