Right.
Which is exactly the same thing I've seen.

Right. This have nothing to do with the bootloader. This is the kernel 
failing to detect the MSCP controller.
ANd it is definitely related to memory size. I've run this under simh, 
so changing memory size is easy. And it does fail when you have too much 
memory.

I was planning to look into it a couple of years ago, but then I got 
stalled with just the generic issue with native builds, and I gave up on 
the whole thing.

As I recently wanted to test things again, I booted my simh instance up 
again, but the last test actually broke all of userland, so currently 
I'm even more broken.

*sigh*

I'll see if I can repair my system and play around a bit more...
