The /init.rc in the android image calls:
	mount ext3 /dev/block/mmcblk0p2 /data nosuid nodev
So you will need ext3 on that partition, or you will need to edit that 
line in init.rc.

The advice to use ext2 is based on deep seated but outdated fears about 
the limited write life of flash devices. I say this having used ext3 for 
rootfs on CF cards for several years with no ill effects.
