Thanks, but the rationale was really deeply buried in the bug reports 
rather than in the Debian changelog, which would have been more helpful 
if it stated what the change was to support and what modules would no 
longer be in the Debian kernel package as a result.

My Athlon64 machine's onboard sound had one of its inputs fail and I 
wanted to use the Soundblaster Audigy card from this machine. Although I 
like building custom kernels, it is also really helpful to be able to 
run a stock kernel to compare things if a custom kernel has a problem.

Regards,

Arthur.
