I've been trying for 2 days now to boot debian (not easy-debian) but a full debian http://elektranox.org/n900/index.html on the N900, using maemo kernel and a memory card, but I always get failed to mount device guru meditation error. My debian.item looks like this

ITEM_NAME="Debian"
ITEM_ID="debian"
ITEM_DEVICE="${EXT_CARD}p3" (I also have NITdroid on the sd)
ITEM_MODULES="mbcache jbd ext3"
ITEM_FSTYPE="ext3"
ITEM_FSOPTIONS="noatime,rw"

I have tried without quotes, adding errors=remount-ro
I have also tried copying the kernel from maemo to the memory card again but I see nothing different

Has anyone done this before? Do you see any obvious mistake?
