ok i was having boot issues so heres how i fixed it. i installed gingerbread to emmc while the microsd card was in, now i cant get it to boot to gingerbread with the card in even if i use ITEM_DEVICE={INT_CARD}p2 if i take the card out it boots fine with ITEM_DEVICE=mmcblk0p2 but i would love to be able to boot it with the card in. so when i changed it to ITEM_DEVICE=mmcblk1p2 it boots with the card in. problem solved!
