The installer puts all of Android in NAND. After installation the SD card is
only used for extra storage (web downloads, media, etc.) Any FAT formatted
SD card will do. You can run with no SD card in there, but as I recall, some
things don't work.

It should boot other distributions from SD. The modification is because
Andoid uses a different NAND partition layout. If you want to replace
Android with a different distribution in NAND, you should reflash Qi.

Hope that helps!
