Sorry to disappoint you, but the ONLY difference between 1.28.4.2 and 1.29
is the allowance of unit numbers higher than 1, which I have already
incorporated.  Here's the proof (note that /usr/src/NetBSD-current/ is
actually version 1.2.1 at the moment):

(which actually keeps a limit of 2 floppy devices.)
And the symptoms aren't at all consistent.  I've been adding printf() code
to help me debug the beast, but in the present incarnation the computer
reboots as soon as it runs the boot code (no messages).  In a previous
incarnation, it prompted for the kernel file but rebooted immediately after
loading the text segment.  How am I supposed to debug the d----d thing if
any debugging code I add changes the symptoms?
