Thanks, added a link to the wiki.

If you want to, feel free to grab the datasheet and add dump support.
Nothing complex, just a bit time-consuming...

Interesting. I can't find a datasheet for the LPC47B387, so dump support
won't happen anytime soon. But it would be nice if you could re-run
'superiotool -V' on that box with my latest patch applied
([PATCH] superiotool: Various improvements). That should tell us the
Super I/O ID, I hope, so we can at least detect the chip.
