I had a really hard time getting the remote to work with the new in kernel
code.  My current understanding is that you have the in kernel code (a
couple buttons will "just work" in Myth now) and then there is a bridge to
lirc where you can make what buttons you want to a key table.  So it goes
kernel -> keytable -> lirc.  You should be able to see the key down and key
up events with ir-keytable.  My guess is the lirc keymap you are using is
not the one you want, for Gentoo you would make changes to
/etc/lirc/lircd.conf to map the hex codes ir events to the buttons

# ir-keytable -t
1305965079.604337: event MSC: scancode = 1f
1305965079.604343: event key down: KEY_PAUSECD (0x00c9)
1305965079.604344: event sync
1305965079.604357: event key up: KEY_PAUSECD (0x00c9)
1305965079.604357: event sync
1305965079.604361: event MSC: scancode = 1f
1305965079.604362: event key down: KEY_PAUSECD (0x00c9)
1305965079.604362: event sync
1305965079.604363: event key up: KEY_PAUSECD (0x00c9)
