I'm trying to get generic distro kernels to work, so not so keen on this one

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)
