It doesn't work with the latest (Linus) 2.6-test and > radeonfb. Do you have any special patches in your tree for radeonfb? No, I told you to use _my_ 2.6 tree which contains a new radeonfb that have not yet been merged upstream. bk://ppc.bkbits.net/linuxppc-2.5-benh or rsync from source.mvista.com::linuxppc-2.5-benh > BTW: It took me quite a while to figure out that the only working image > with yaboot was the zImage.chrp.

Yaboot normally loads a plain vmlinux, though if you are using tftp, you need to modify yaboot to be able to d/l more than 4Mb (edit fs_of.c and change the allocated size). The ELF image should work, at least the one produced by my tree does, it's possible that there's a similar size problem with the one in Linus tree, a few of those recent changes haven't yet made it to Linus.
