Nevermind, I found the schematic on their wordpress blog. I think I've got them beat -- how about hardware-level switching between 18b and 24b color, using a single GPIO pin? <g>
Don't worry about Olimex, my idea uses different buffer chips, in a different way, and the buffer scheme is really the only part of the design that they "own" (if at all -- there's no license info or anything on the blog post...) so I think we should be in the clear there.
I'll have schematics up in a bit...

chris this is awesome. suggestion: if you have the experience and knowledge could you look at selecting and designing in suitable buffers on the RGB/TTL lines? there's a schematic from olimex which does this (doesn't use R-2R uses 1x 2x 4x 8x etc. resistors) which i'd like to use but it's an "attribution" license which is incompatible with the GPL.
