It was indeed set to 115200 N81, but I just experimented a bit and found
that it worked on 19200 baud (with some garbage at the top, though). :)

So I just recompiled and reburned LinuxBIOS with maximum logging, and I
got this:

I guess that's a pretty good indication that RAM isn't working, right?

So to get back to debugging this, do you have any idea of a time when
the 8601 code was working? Was it while LinuxBIOS existed in Subversion
(there was a CVS repo some years ago, wasn't there)?
