I've been having issues with pommed on my macbook pro 5,5. The keyboard
backlight will initially come on, but after the configured keyboard idle
timeout is reached, the backlight will not come on again regardless of
activity. This was happening with my system installed package
(1.35~maverick-mactel1). I cloned the git repo and began to hack around to
debug a bit. I tracked down the issue to the following snippet:

+ logdebug(" -> Internal keyboard - fd=%02d\n", fd);
internal_kbd_fd = fd;
}
When testing with the added debug statement, I was finding that the "fd" was
"6", but the "internal_kbd_fd" was "5". I don't presume to understand what
this means or why it is occurring. Removing the conditional around that
block appears to resolve my issue, as the outer conditional appears to
ensure that we are catching a keyboard event.
Here is a debug log after my changes were applied. Look at the end to see
the keypresses (ctrl-c) and what the events are that are being seen.
