I'm hoping to get rid of that requirement for the reasons above, and I'm wondering if we've already got that far (Florian said he had it booting on his XO-1.5, although maybe he figured out the magic parameters and is using them)... So I don't really like any of these solutions. I think we should program this info from inside the kernel (like in my original patch, although I'm open for nicer ways to do the same thing) Daniel
