Ok, I compiled and loaded your new driver, and aside from noise when
compiling, it seems to be working ok.  As an added bonus, I now have one
record channel where there was none before.  Whoo-hoo!

The aforementioned noise from compilation is attached (note that I am
using "-O2 -pipe" in /etc/make.conf - I don't know if that makes a
difference).
