Sure - But i already repartitionated the Card like this:

4 GB SDHC
100MB FAT32 - Primary
2000MB EXT3 - Primary
Empty - for now

Configuration in android.etc.item

ITEM_NAME="Android (external SD, partition 2)"
ITEM_ID="android2"
ITEM_DEVICE="${EXT_CARD}p2"
ITEM_MODULES="mbcache jbd ext3 fat vfat"
ITEM_FSTYPE="ext3"
ITEM_FSOPTIONS="noatime,rw"

I think my Mistake lies somewhere in this Configuration.
