Don't want to get your hopes up again, but I think Papadroid just had him basically re-download and install the files from a different source (wag3slav3's thread, I think) to make sure they were good, clean, whole files. Papadroid, can you confirm?
Did you follow / understand the discussion about using the Clockworkmod custom recovery above? If so, you might be able to use it in place of the recovery.img (Amon_RA's that is, that is used by this thread). Since it apparently doesn't need a trackball, it might work for you. I have no first-hand experience with it though, so I can't really encourage you in that direction if you know what I mean (I've read the same cautions about it posted previously).
