Trying to boot the 1.4.1 installation floppy sets on a pc164, I get a
"kernel stack not valid halt" right after the kernel gets started.
I've read back the floppies and they compare bit-for-bit identical
with the distribution floppy images.

Any clue on what to look at next?  Is there a -current snapshot I
could try? (my goal is to run -current).
