Do you have a serial console?
I tried to mount fixit floppy. looks like floppy controller can't be found either. I should have a serial cable around. Not sure whether it works for PC or not, I used it for debugging ARM. I'll get it back to you tomorrow. Too late today.
In order not to mess up with the mailing list. I'll send it directly to you.
