What can I say, I'm a sucker for new toys... Sadly, I forgot that I was
going to be working from home today when I placed the order, and its being
delivered to the office (probably sitting on my desk by now), but I should
be able to poke at it next week. I don't anticipate this being too bad to
get properly sorted out.

">" == "KEY_DOT + KEY_LEFTSHIFT" (or RIGHTSHIFT), if I'm thinking clearly.
Don't think ir-keytable can push combos though, so you're correct.

My solution was to use lircd in devinput mode and map the keys as needed
in my lircrc.

At the moment though, I'm not actually using *any* IR receivers, I'm using
a TiVo Slide bluetooth remote. :)

That's the part I mentioned earlier about X sucking and not passing keycodes
over 255. KEY_NUMERIC_0 == 0x200 == 512.
