Ah, but the problem is that the modules are on the initrd, and thus you
need to use a initrd tailored to your kernel, or all hell will break
lose in the installation. Furthermore, d-i is currently not yet 2.6
friendly, so 2.4.25 will have to do for now for the install.

Ok, i can always build a UP config then, but if i also do the same for
power3 (you told me that it would maybe not run at all, right), this
would mean 7 configs building in total, and for 1 hour per config build ...
