Huh. Now I'm not quite sure what the heck is going on... One thing that
does need to be fixed in that table though, is 'type: UNKNOWN' should
be 'type: RC-5'.

Bizarre. Seems to have slightly different table files than the package
with the same nvr for fedora 15.

Sorry, I'm an idjit. It is indeed supposed to be
'ir-keytable -a /etc/rc_keymaps.cfg', which you've tried, and got an
error from... I wonder if setting UNKNOWN to RC-5 will get you past
that...
