It is very likely (99%) that 4-bit interface is there and is used for SD cards. I don't think 8 bit mode is there and all 13 MMCmobile pins are present in the connector. This is very new standard and the connector is more complex (2 rows) and it in not very useful right now as cards are not fast enough even to saturate the 4 bit bus. I'm also not sure even 4 bits are used for MMCmobile/plus cards as this is quite new feature in linux (similar to SDHC). I guess best is to use SD cards with stock n800 firmware right now.
