Could you please write precisely how to mount opt folder from second emmc partition? I've tried to uninstall fcam-drivers, but blessn900 depends on this package. So then I've been trying to uninstall blessn900, but I got an error that part of it is located in opt folder which is not accessible. So I probaly must mount this folder.
mount -t ext3 -o rw,noatime /dev/mmcblk0p2 /mnt/maemo/home mount /mnt/maemo/home/opt /mnt/maemo/opt chroot /mnt/maemo
