the evkey entry is only to get the menu KEYS to work, if you can toggle which menu entry to choose evkey is working for you. Partiton info looks right, my guess would be your data was not properly copied.

did you do this?

# apt-get -d install tar
# cd /var/cache/apt/archives/
# mkdir /tar-temp/
# dpkg -x tar*.deb /tar-temp/
# /tar-temp/bin/tar cf - -C /floppy . | /tar-temp/bin/tar xvf - -C /opt


/bin/tar (busybox) will not copy things properly. If it can not boot from mmc it will boot from flash I believe. http://penguinbait.com/tar.gz is the one I use.
