I was over at the miui-dev forums and found a thread over at XDA about flashable fonts. The first link I couldn't get any of them to work on my D-1 but the second as ones specifically designed for MIUI and they work great.

just plop the zip on your SDcard and flash with clockwork and they come out great.
