Sure, I burned it to a CDROM and booted from that per SRM. The screen
went black for a second, then the SRM console came back with:

?05 HLT INSTR
PC=00000000.20000014 PSL= 00000000.00000007

I wonder if we would be able to see more on a serial line - I can try
that perhaps tomorrow or at the weekend. To find out to what code the
PC is pointing to, I would need to understand to what point in memory SRM
loads the image into.... But this way, the process of loading the kernel
definitely worked - I still don't understand why aboot can load the
old kernel but not the new one. I'll have a look at the aboot sources,
perhaps there's a certain limit on kernel size?

I'm not sure if we can call this progress,
CU,
Uli
