Weeeeeell...
First, THANXS GUYS! BOOTING NITDROID ROCKS! Yes, a little bit slow (perhaps allowing us to overclock could help until GPU drivers ) BUT...
After powering off nitdroid, trying to reboot, choosing again option 4... boot loader always stop after trying to access ext3, going again to boot menu!
Why first time it works but now, unable to boot nitdroid again??
I'm a lot of bits confused!

ANYWAY, THAT FEW MOMENTS WITH ANDROID ON MY SCREEN WERE WONDERFULL!! (Are you genious or somethig like that???)
Waiting for a lammer version , since I can't handle WHY only one Android boot for me.
