Well that's not so hot. Probably some sort of wiring missing somewhere
in ir-sysfs.c in that kernel. The code in question has been updated
considerably since, which explains why this works for me and doesn't
for you. Not sure what to suggest here right now. Ah! Get v4l-utils
installed (v0.8.1 or later), then use ir-keytable to clear the
in-kernel keytable. (ir-keytable -d rc0 -c, iirc). Its a hack-around,
but it should work... (if there's no keytable to look up decoded
scancodes against, no keys will come through the input layer). The
other route you could go is to use lircd's devinput config and driver,
listening to the streamzap receiver's /dev/input/eventX device, and
ignore the raw IR coming from the lirc interface.
