successfully installed 12.04 ubuntu desktop with select directory as target !!!!
finally it looks like my problem was my card reader.

REVISION: last
MICROSD: 8 Gb, class 10
BOOTLOADER: Pali's U-Boot
IMAGE_SOURCE: ubuntu-desktop
FIRMWARE: meego
dist_upgrade: 0

no problem at boot, after logging, just the desktop background but keyboard is working (where is ALT key?)
anyway a give a try on lubuntu.
