I can confirm fabio78's results works well on d620. using -v -f cpus=2 (or cpus=1) arch=i386. (sometimes if she will not find the catch then replace -f for -x then back after next boot)
no: battery meter, wifi, sleep, or trackpad /keyboard... yet and restart needs "fix" but iboot (chameleon, stolen and rebranded) does not accommodate it like chameleon
