to flash i've simply removed some applications like abiword, scite, dillo, sylpheed, xmms and xpdf from the initrd.bin, so i've created a new initrd.bin from the files
and effectively, the problem was the kernel, i've taken the tetsu kernel and i've at least the first pinguin
but now it complains about esaseblock not readable
so my problem is the mkfs.jffs2 call that's wrong, i'll look further
