A further comment.

I suspect that your problem might be due to the way you compile modules 
with Linux 2.6.7. If that is the case you should study a bit one of the 
making way for the examples found in showroom/v3.x/kern.

I've just compiled an old examples found in the 24.1.x series and it has 
no problem with the fifo handler.
