I installed rockbox r18132 with loader2 from the ipodlinux project and it works!
I'm seeing rockbox running in my ipod for the first time and I already love it! Now to get all my vorbis files in it.
staen, if you find the tweaked rockbox bootloader, I would be glad if you send it to me, loader2 works, but I'd like the rockbox one anyway. Thanks for everything though, even if you don't find it.
