I'd still like to see a comment that only the 405 models have been
tested, and that the 440 model support is theoretical.

If the OpenBlockS266 works, I think it's fair to assume at this stage
that the other 405GP models will work. Once you commit the patches, I
can double check on my Walnut.

As long as always having MULTIUIC enabled doesn't have a noticeable
performance impact on the single UIC devices (not sure what the best way
of verifying that it!), I don't have a problem always using MULTINIC in
the interest of clearer code.
You'll need to add the uic_add() calls for all other 4xx ports, but I
think it would be the same for each (all 405GP/GPr based)?
