Have you tried Z4ROOT or ONE-CLICK? I'm going to spend the day trying to figure this out. Odds are against me, so I may just take my time.
Also it would be awesome if the devs over on Xda would be able to take a crack at it and brewing up a Rom. I doubt it considering the low end processor specs and no flash support. I don't know if there is a workaround besides SkyFire.
