Do you also have the .config file for it, so we can check what is the
problem for us ?

Cool, this would be of interest to us too. Nice it is GPLed from Leigh,
let's see what use we can make from it. Maybe ship it in mkvmlinuz ?

Let's just try to boot the kernel first, without doing that, it won't
help much. argument for the console are as below, we need to get serial
log output to know what is going wrong.

Yep, but see if the above method is not working.

Fine test it, i hope it works, not sure it has serial log builtin, but
let's give it a try. You would need to build the initrd though.

Well, if you had a pmac, you would face no such problems, Or if you had
some less supporteed alpha, sparc or even i386, you would have the same
problems. That said, once we fix it for you, it will become easier for
other prep users too. Also, i naturally accept donation of prep hardware
for doing this kind of stuff in advance :)
