Hi Jim,

In short, yes.

atm, I've this udev rule,

	cat /etc/udev/rules.d/70-infrared.rules
		ACTION=="add", SUBSYSTEM=="rc",
		RUN+="/usr/bin/ir-keytable --clear --protocol=LIRC
		--write=/etc/rc_keymaps/my_streamzap_rpi"

which ensures after boot

	ir-keytable
	Found /sys/class/rc/rc0/ (/dev/input/event2) with:
	        Driver streamzap, table rc-streamzap
	        Supported protocols: LIRC 
	        Enabled protocols: LIRC 
	        Repeat delay = 500 ms, repeat period = 125 ms

which correlates to

	cat  /sys/class/rc/rc0/protocols 
		[lirc]

i.e., the same effect as the manual intervetion of

	echo lirc > /sys/class/rc/rc0/protocols

nonetheless, that _alone_, does NOT 'do the trick'.  if those MCE*
kernel mods are around, i.e., if I have NOT disabled them in the kernel
(re)compile, or, similarly, use the distro-provided kernel which
compiles the mods by default, then -- at boot -- the Streamzap is
recognized/assigned as an MCE keyboard/remote.
