That's very interesting, but I'm unlikely to have time to folow up in the next few weeks. (I'm already investigating the full m68k support qemu is growing in the q800 branch Laurent Vivier's doing on gitorious. So far it prints 3 lines and then dies, but that's more than it was doing before. Those are three lines of kernel boot messages! I need to enable early_printk and verbose...) Still: bookmarked.

Is there a strong reason nommu kernel's won't run on hardware or an emulator that _does_ implement an mmu?
