yes, I did all of this. and I was able to flash correctly! I just mounted both the original (mmcblk0p2) and the destination (mmcblk1p2) on /opt and /floppy, and used ./tar cf - -C /floppy . | ./tar xvf - -C /opt. worked like a bliss! I did format the card using sfdisk beforehand, and formatted mmcblk1p2 to ext2 before copying. after this, I just switched cards, and all was perfect. I still didn't figure out how acronis worked... oh well! thanks for assistance though.
